NOTES:

1.   ACCOUNTING POLICIES

     The consolidated interim condensed financial statements have been prepared
     in accordance with International Accounting Standards ("IAS") 34 "Interim
     Financial Reporting". The accounting policies and methods of computation
     used in the preparation of the consolidated interim condensed financial
     statements are consistent with those used in the preparation of the
     financial statements for the year ended December 31, 2004 except for the
     ones modified by the Company as a result of the adoption of the new revised
     International Financial Reporting Standards ("IFRS").

     In 2005, the Group adopted the new revised IFRS below, which are relevant
     to its operations. The 2004 comparative numbers have been amended as
     required, in accordance with the relevant requirements. The adoption of the
     IFRS did not result in substantial changes to the Group's accounting
     policies. In summary:

     --   IAS 1 and 27 (both revised in 2003) has affected the presentation of
          minority interests. IAS 1 (revised in 2003) also has affected the
          presentation of share of profit of associates and requires the
          disclosure of critical accounting estimates.

     --   IAS 2, 8, 10, 16, 17, 21, 28, 32, 33 (all revised in 2003) and 39
          (revised in 2004) and IFRS 2 had no material effect on the Group's
          policies.

     --   IAS 24 (revised in 2003) has affected the identification of related
          parties and some other related-party disclosures. (See the revised
          accounting policy below)

                                       4


     --   IFRS 5 has resulted in a change in the accounting policy relating to
          the recognition of assets held for sale or discontinued operation,
          which did not have any material impact on the results and financial
          positions of the Group as the Group did not hold material assets in
          this category during the periods presented.

     --   The Group has early adopted IFRS 6, which did not require a change in
          the accounting policies for exploration and evaluation activities.

     Related parties include China National Petroleum Corporation ("CNPC") and
     its subsidiaries, other state-controlled enterprises and their subsidiaries
     directly or indirectly controlled by the PRC government, corporations in
     which the Company is able to control or exercise significant influence, key
     management personnel of the Company and CNPC and their close family
     members.

     The consolidated interim condensed financial statement presented herein
     should be read in conjunction with the consolidated financial statements
     and notes thereto included in the annual report of the Group for the year
     ended December 31, 2004. The consolidated interim condensed financial
     statements as of June 30, 2005 and for the six-month periods ended June 30,
     2005 and June 30, 2004 included herein are unaudited but reflect, in the
     opinion of the Board of Directors, all adjustments (which include only
     normal recurring adjustments) necessary to properly prepare the
     consolidated interim condensed financial statements, in all material
     respects, in accordance with IAS 34. The results of operations for the six
     months ended June 30, 2005 are not necessarily indicative of the results of
     operations expected for the year ending December 31, 2005.

     Costs that were incurred unevenly during the financial year are anticipated
     or deferred in these consolidated interim condensed financial statements
     only if it would be also appropriate to anticipate or defer such costs at
     the end of the financial year.

     Income tax expense is recognized based on the best estimate of the weighted
     average annual income tax rate expected for the full financial year. The
     estimated average annual tax rate used for the six months ended June 30,
     2005 is principally 25% (six months ended June 30, 2004: 27%).

     In accordance with the acquisition agreement between the Company and CNPC
     dated March 28, 2005, the Company has acquired the petroleum and natural
     gas-related refinery and petrochemical businesses respectively owned by
     CNPC's wholly-owned subsidiaries, Ningxia Dayuan Refinery and Petrochemical
     Company Limited ("Dayuan") and Qingyang Refinery and Petrochemical Company
     Limited ("Qingyang"), from CNPC for which the Company paid a cash
     consideration of RMB9.14 million. The RMB9.14 million purchase price was
     included as payable to CNPC at June 30, 2005.

     The acquisition is a combination of businesses under common control since
     the Company and the CNPC's refinery and petrochemical businesses owned by
     Dayuan and Qingyang are under the common control of CNPC. As a result, the
     Company has accounted for the acquisition in a manner similar to a uniting
     of interests, whereby the assets and liabilities acquired are accounted for
     at historical cost to CNPC (net liabilities of RMB183 million at the
     effective date). The consolidated financial statements have been restated
     to give effect to the acquisition with all period presented as if the
     operations of the Company and these refinery and petrochemical businesses
     have always been combined. The difference between RMB9.14 million paid and
     the net liabilities transferred from CNPC has been adjusted against equity.

                                       5


     The summarized results of operations for the refinery and petrochemical
     businesses and on a consolidation basis for the six months ended June 30,
     2004 are set out below:

2.   CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

     Estimates and judgments are continually evaluated and are based on
     historical experience and other factors, including expectations of future
     events that are believed to be reasonable under the circumstances.

     The matters described below are considered to be the most critical in
     understanding the judgments that are involved in preparing the Group's
     financial statements:

     (a)  ESTIMATION OF OIL AND NATURAL GAS RESERVE

          Oil and gas reserves are key elements in the Group's investment
          decision-making process. They are also an important element in testing
          for impairment. Changes in proved oil and natural gas reserves,
          particularly proved developed reserves, will affect unit-of-production
          depreciation charges to income. Proved reserve estimates are subject
          to revision, either upward or downward, based on new information, such
          as from development drilling and production activities or from changes
          in economic factors, including product prices, contract terms or
          development plans. In general, changes in the technical maturity of
          oil and gas reserves resulting from new information becoming available
          from development and production activities have tended to be the most
          significant cause of annual revisions. Changes to the Group's
          estimates of proved reserves, particularly proved developed reserves,
          may affect the amount of depreciation, depletion and amortization
          recorded in the Group's financial statements for property, plant and
          equipment related to oil and gas production activities. A reduction in
          proved developed reserves will increase depreciation, depletion and
          amortization charges (assuming constant production) and reduce net
          income.

     (b)  ESTIMATED IMPAIRMENT OF PROPERTY, PLANT AND EQUIPMENT

          Property, plant and equipment, including oil and gas properties are
          reviewed for possible impairment when events or changes in
          circumstances indicate that the carrying amount may not be
          recoverable. Determination as to whether and how much an asset is
          impaired involves management estimates on highly uncertain matters,
          such as future prices of crude oil, refined products and chemical
          products, production profile, etc. However, the impairment reviews and
          calculations are based on assumptions that are consistent with the
          Group's business plan. These assumptions also include those relative
          to the pricing regulations by the regulatory agencies in China that
          the policies will not restrict the profit margins of refined products
          to levels that will be insufficient to recover the carrying cost of
          the related production assets. Favourable changes to some assumptions
          might have avoided 

                                       6


          the need to impair any assets in these periods, whereas unfavourable
          changes might have caused an additional unknown number of other assets
          to become impaired.

3.   TURNOVER

     Turnover represents revenues from the sale of crude oil, natural gas,
     refined products and petrochemical products and from the transportation of
     crude oil and natural gas. Analysis of turnover by segment is shown in Note
     9.

     equipment.

     The tax on the Group's profit before taxation differs from the theoretical

     In preparing the summary of differences between IFRS and US GAAP,
     management is required to make estimates and assumptions that affect the
     reported amounts of assets and liabilities, the disclosure of contingent
     assets and liabilities, and the estimates of revenues and expenses.
     Accounting estimates have been employed in these financial statements to
     determine reported amounts, including realizability, useful lives of
     tangible and intangible assets, income taxes and other areas. Actual
     results could differ from those estimates.

     A summary of the principal differences and additional disclosures
     applicable to the Group is set out below:

     (a)  REVALUATION OF PROPERTY, PLANT AND EQUIPMENT

          The property, plant and equipment, excluding oil and gas reserves,
          transferred to the Company by CNPC were appraised as of June 30, 1999,
          as required by the relevant PRC regulations, by a firm of independent
          valuers registered in the PRC, China Enterprise Appraisal. As at
          September 30, 2003, a revaluation of the Group's refining and chemical
          production equipment was undertaken by a firm of independent valuers
          registered in the PRC, China United Assets Appraiser Co., Ltd, on a
          depreciated replacement cost basis.

          The June 1999 revaluation resulted in RMB80,549 million in excess of
          the prior carrying value and a revaluation loss of RMB1,122 million on
          certain property, plant and equipment.

          The September 2003 revaluation resulted in RMB872 million in excess of
          the carrying value of certain property, plant and equipment
          immediately prior to the revaluation and a revaluation loss of
          RMB1,257 million.

          The depreciation charge, which includes impairment charge, on the
          revaluation surplus from January 1, 2005 to June 30, 2005 was RMB3,436
          million, and from January 1, 2004 to June 30, 2004 was RMB4,391
          million.

          The depreciation charge, which includes impairment charge, on the
          revaluation loss from January 1, 2005 to June 30, 2005 was RMB127
          million, and from January 1, 2004 to June 30, 2004 was RMB465 million.

          The loss on disposal of revalued property, plant and equipment from
          January 1, 2005 to June 30, 2005 was RMB2 million, and from January 1,
          2004 to June 30, 2004 was RMB47 million.

                                       14


          For purposes of reconciling to the US GAAP financial data, the effect
          of the revaluation, the related depreciation charges and loss on
          disposal is reversed. A deferred tax asset relating to the reversal of
          the effect of revaluation in 1999 is established, together with a
          corresponding increase in the shareholders' equity. Under a special
          approval granted by the Ministry of Finance, the effect of the
          revaluation in 1999 is available as additional depreciation base for
          purposes of determining taxable income.

     (b)  ONE-TIME REMEDIAL PAYMENTS FOR STAFF HOUSING

          The Ministry of Finance of the PRC issued several public notices and
          regulations during the year ended December 31, 2000 and 2001 with
          respect to the one-time remedial payments for staff housing payable to
          certain employees who joined the workforce prior to December 31, 1998
          and have housing conditions below local standards as determined in
          accordance with government regulations and guidelines. These Ministry
          of Finance notices and regulations also provided that the portion of
          remedial payments attributable to the periods prior to a restructuring
          of the employer enterprise from a wholly state-owned status to a less
          than wholly state-owned status is to be borne by the state shareholder
          of the enterprise.

          The restructuring that resulted in the formation of the Group took
          place in November 1999. As such, the one-time remedial housing
          payments payable to the eligible employees of the Group are to be
          borne by the state shareholder of the Group.

          Under IFRS, such direct payments to employees or reimbursements will
          not be recorded through the consolidated profit and loss account of
          the Group. US GAAP contains no such exemption but requires this
          principal shareholder's action on behalf of the Company to be recorded
          in the consolidated profit and loss account. In the last quarter of
          year 2002, the Group and CNPC completed the process of estimating the
          amount payable to qualified employees of the Group. This amount,
          RMB2,553 million, was reflected in determining net income of the Group
          for the year ended December 31, 2002, under US GAAP. Since this amount
          is borne by CNPC, a corresponding amount has been included as an
          addition to the other reserves in the shareholders' equity of the
          Group. There were no significant changes in this estimate during 2004
          and the first half of 2005.

     (c)  MINORITY INTERESTS

          In accordance with the revised IAS 1 and IAS 27, minority interests
          becomes part of the profit for the period and total equity of the
          Group, whereas under US GAAP, it is respectively excluded from the net
          income and shareholders' equity of the Group. In addition, this
          reconciling item also includes the impact of minority interest's share
          of the revaluation gain and loss, on the property, plant and equipment
          of non-wholly owned subsidiaries, to net income and shareholders'
          equity under US GAAP.

     (d)  RECENT US ACCOUNTING PRONOUNCEMENTS

          In December 2004, the Financial Accounting Statements Board ("FASB")
          revised the Statement of Financial Accounting Standards No. 123 --
          "Share-Based Payment" ("FAS 123(R)"). FAS 123(R) requires all
          share-based payments to employees, including grants of employee stock
          options, to be recognized in the financial statements based on their
          fair values. Pro forma disclosure is no longer an alternative to
          financial statement recognition. FAS 123(R) is effective as of the
          beginning of the company's first fiscal year that begins after June
          15, 2005. The Group is evaluating the transition provisions allowed by
          FAS 123(R). The Group does not expect the adoption of FAS 123(R) to
          have a material impact on the Group's financial position or
          operational results.

          On November 24, 2004, the FASB issued Statement No. 151, "Inventory
          Costs", an amendment of ARB No. 43, Chapter 4 (FAS 151). FAS 151
          requires that abnormal amounts of idle capacity and spoilage costs be
          excluded from the cost of inventory and expensed when incurred. The
          provisions of FAS 151 are applicable to inventory costs incurred
          during fiscal years beginning after June 15, 2005. The Group does not
          expect the 

                                       15


          adoption of FAS 151 to have a material impact on the Group's financial
          position or results of operation.

          On December 15, 2004, the FASB issued Statement No. 153, "Exchanges of
          Non-monetary Assets", an amendment of APB Opinion No. 29 (FAS 153).
          FAS 153 requires exchanges of productive assets to be accounted for at
          fair value, rather than at carryover basis, unless (1) neither the
          asset received nor the asset surrendered has a fair value that is
          determinable within reasonable limits or (2) the transactions lack
          commercial substance. FAS 153 is effective for non-monetary asset
          exchanges occurring in fiscal periods beginning after June 15, 2005.
          The Group does not expect the adoption of FAS 153 to have a material
          impact on the Group's financial position or results of operation.

          In May 2005, the FASB issued FAS No. 154, "Accounting changes and
          Error Corrections" (FAS 154) which replaces APB Opinion No. 20
          "Accounting Changes" and FAS No. 3, "Reporting Accounting Changes in
          Interim Financial Statements-An Amendment of APB Opinion No. 28". FAS
          154 provides guidance on the accounting for and reporting of
          accounting changes and error corrections. It establishes retrospective
          application or the earliest date practicable as the required method
          for reporting a change in accounting principle and the reporting of a
          correction of an error. FAS 154 is effective for accounting changes
          and corrections of errors made in fiscal years beginning after
          December 15, 2005. The Group is currently evaluating the effect that
          the adoption of FAS 154 will have on its consolidated results of
          operations and financial condition but does not expect it to have a
          material impact.


MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

The following discussion should be read in conjunction with the consolidated
interim condensed financial statements for the Group and the notes thereto
contained in the information required under paragraphs 46(1) to 46(9) of
Appendix 16 to the Rules Governing the Listing of Securities on The Stock
Exchange of Hong Kong Limited (the "LISTING RULES") which will be submitted to
the Hong Kong Stock Exchange ("HKSE") for publication on the website of the
HKSE.


OVERVIEW

For the six months ended June 30, 2005, the profit before taxation of the Group
was RMB85,467 million, representing an increase of 33.7% from the corresponding
period of last year. Net profit was RMB61,624 million, representing an increase
of 36.1% from the corresponding period of last year. The continued rapid
improvement of the Company's operating results was primarily attributable to the
optimal use of its competitive edge in upstream activities, streamlining of its
downstream structures, speeding up of the construction of pipelines and
enhancement of operation management during a period of sustained high oil
prices.

For the six months ended June 30, 2005, the Company's basic and diluted earnings
per share was RMB0.35.


COMPARISON BETWEEN THE SIX-MONTH PERIOD ENDED JUNE 30, 2005 AND THE SIX-MONTH
PERIOD ENDED JUNE 30, 2004

CONSOLIDATED OPERATING RESULTS

Turnover   Turnover increased 41.5% from RMB178,404 million for the six months
ended June 30, 2004 to RMB252,489 million for the six months ended June 30,
2005. The growth was mainly attributable to the increases in the prices and
sales volume of crude oil, refined oil and petrochemical products, and the
increase in the sales volume of natural gas.

Operating Expenses   Operating expenses increased 46.3% from RMB114,148 million
for the six months ended June 30, 2004 to RMB166,952 million for the six months
ended June 30, 2005. The 

                                       16


change was mainly attributable to an increase in the purchase costs of raw and
auxiliary materials such as crude oil and refined products from external
suppliers and an increase in exploration expenses due to increased exploration
activities.

Purchases, Services and Other Expenses   Purchases, services and other expenses
increased 87.9% from RMB51,272 million for the six months ended June 30, 2004 to
RMB96,362 million for the six months ended June 30, 2005. This was primarily due
to the increase in the purchase costs of crude oil and refined products resulted
from the rise in prices of raw and auxiliary materials for such crude oil and
refined products, as well as from our increased consumption of raw materials to
meet the rise in output of refinery and petrochemical products. In addition, the
increase in trading volume during the period led to a corresponding increase in
purchase expenses.

Employee Compensation Costs   Employee compensation costs rose 21.4% from
RMB10,540 million for the six months ended June 30, 2004 to RMB12,800 million
for the six months ended June 30, 2005. This was primarily due to the
improvement in the Company's operating results which led to the increase in the
wages and welfare expenses of staff and workers; as well as the further
development of the Company's retail network which led to the increase in labour
service costs.

Exploration Expenses   Exploration expenses increased 51.5% from RMB5,630 
million for the six months ended June 30, 2004 to RMB8,528 million for the six 
months ended June 30, 2005. This was mainly due to the Company appropriately 
increasing its input relating to oil and gas exploration when oil prices were 
high.

Depreciation, Depletion and Amortization   Depreciation, depletion and
amortization increased 4.2% from RMB24,746 million for the six months ended June
30, 2004 to RMB25,791 million for the six months ended June 30, 2005. This was
mainly attributable to an increase in the amount of property, plant and
equipment which led to a corresponding increase in depreciation and depletion.

Selling, General and Administrative Expenses   Selling, general and 
administrative expenses increased 7.8% from RMB12,794 million for the six months
ended June 30, 2004 to RMB13,797 million for the six months ended June 30, 2005.
This was primarily due to an increase in transportation expenses caused by an 
increase in the sales volume of refined products.

Taxes other than Income Tax   Taxes other than income tax increased 13.2% from
RMB9,417 million for the six months ended June 30, 2004 to RMB10,660 million for
the six months ended June 30, 2005. The increase was primarily due to an
increase in consumption tax and surcharges as a result of an increase in the
sales volume of gasoline and diesel oil by the Group's refineries and also an
increase in compensation fees for mineral resources due to an increase in crude
oil and natural gas revenues.

Profit from Operations   As a result of the factors discussed above, profit from
operations increased 33.1% from RMB64,256 million for the six months ended June
30, 2004 to RMB85,537 million for the six months ended June 30, 2005.

Net Exchange Gain   The net exchange gain increased from RMB10 million for the 
six months ended June 30, 2004 to RMB80 million for the six months ended 
June 30, 2005. This was primarily due to a depreciation of the value of the 
Japanese Yen and the Euro against Renminbi during the first half of this year.

Net Interest Expenses   Net interest expenses decreased 32.5% from RMB960 
million for the six months ended June 30, 2004 to RMB648 million for the six 
months ended June 30, 2005. The decrease in net interest expenses was primarily 
due to a decrease in the average proportion of interest-bearing debts which led 
to the decrease in interest expenses and sufficient cash flow generated from 
operating activities which led to the increase in interest income.

Profit Before Taxation   Profit before taxation rose 33.7% from RMB63,909 
million for the six months ended June 30, 2004 to RMB85,467 million for the six
months ended June 30, 2005.

ended June 30, 2004 to RMB23,246 million for the six months ended June 30, 2005.
The increase was mainly due to an increase in taxable profits.

Net Profit   As a result of the factors discussed above, net profit increased
36.1% from RMB45,276 million for the six months ended June 30, 2004 to RMB61,624
million for the six months ended June 30, 2005.

year increased 39.8% from RMB65,870 million for the six months ended June 30,
2004 to RMB92,099 million for the six months ended June 30, 2005. This

financing activities increased 77.6% for the six months ended June 30, 2005.

As at June 30, 2005, the debt to capitalization ratio (debt to capitalization
ratio = total debts/(total debts + total equity)) was 11.9% (13.3% as at
December 31, 2004).


CAPITAL EXPENDITURES

                                       21


The table below sets out our capital expenditures by business segments for each
of the six months ended June 30, 2005 and the six months ended June 30, 2004.
During the first half of 2005, capital expenditures increased 10.1% from
RMB28,691 million for the six months ended June 30, 2004 to RMB31,592 million
for the six months ended June 30, 2005. The increase in capital expenditure was
primarily due to the appropriate increase in expenditure relating to oil and gas
exploration and development when oil prices were high. Further, the price of
production raw materials, such as steel, fuel, water and electricity, increased
which led to an increase in investment.

* If geological and geophysical exploration costs were included, the capital
expenditures and investments for the Exploration and Production segment for the
first half of 2004 and the first half of 2005, and the estimate of the same for
the entire 2005 would be RMB21,646 million, RMB24,028 million and RMB66,660
million, respectively.


EXPLORATION AND PRODUCTION

The majority of the Group's capital expenditures is related to the Exploration
and Production segment. For the six months ended June 30, 2005, capital
expenditures in relation to exploration and production amounted to RMB20,630
million, including RMB3,727 million for exploration activities and RMB15,953
million for development activities. For the six months ended June 30, 2004,
capital expenditures in relation to this segment totalled RMB19,146 million,
including RMB3,665 million for exploration activities and RMB14,481 million for
development activities. The increase in capital expenditures was mainly due to
the increased expenditures relating to oil and gas exploration and development.

It is estimated that for the twelve months ending December 31, 2005, capital
expenditures of the Group in the Exploration and Production segment will amount
to RMB61,160 million. Approximately RMB10,960 million is expected to be used for
oil and gas exploration, and approximately RMB50,200 million will be used for
oil and gas development. Exploration and development is expected to be mainly
carried out in the Erdos, Junggar, Tarim, Songliao, Sichuan and Bohai Bay
basins.


REFINING AND MARKETING

For the six months ended June 30, 2005, capital expenditures of the Group in the
Refining and Marketing segment amounted to RMB4,614 million, of which RMB2,487
million was spent on the expansion of the retail marketing network of our
refined products and storage infrastructure facilities, and RMB1,181 million was
spent on upgrading our refining facilities. For the six months ended June 30,
2004, capital expenditures for this segment totalled RMB4,526 million. The
capital expenditures during this period were basically the same as that during
the same period last year.

                                       22


It is estimated that capital expenditures of the Group for the Refining and
Marketing segment for the twelve months ending December 31, 2005 will amount to
RMB14,590 million, including approximately RMB7,250 million to be spent on
construction and expansion of refining facilities; and approximately RMB7,340
million to be spent on investments in our refined product retail marketing
network.


CHEMICALS AND MARKETING

For the six months ended June 30, 2005, capital expenditures in the Chemicals
and Marketing segment were RMB2,633 million, compared with RMB1,062 million for
the six months ended June 30, 2004. The increase in capital expenditures was
mainly because the ethylene upgrading and expansion project of Lanzhou
Petrochemical Company, the propylene projects of Daqing Refinery and
Petrochemical Company and Dalian Petrochemical Company and the PTA project of
Liaoyang Petrochemical Company, amongst other projects, were in their peak
construction period.

It is estimated that for the twelve months ending December 31, 2005, capital
expenditures of the Group in the Chemicals and Marketing segment will amount to
RMB8,350 million. The capital expenditures are expected to mainly be used for
upgrading ethylene facilities in Daqing, Jilin, Lanzhou and Dushanzi, and the
PTA project of Liaoyang Petrochemical Company.


NATURAL GAS AND PIPELINE

For the six months ended June 30, 2005, capital expenditures in the Natural Gas
and Pipeline segment amounted to RMB3,651 million. RMB3,375 million of these
expenditures was spent on construction of long distance pipelines and RMB2,327
million of such amount was spent on the West-East Gas Pipeline project. For the
six months ended June 30, 2004, capital expenditures in the segment totalled
RMB3,905 million. The decrease in capital expenditures was mainly due to a
dramatic decrease in expenditures relating to the second Shaanxi-Beijing
Pipeline Project.

It is estimated that for the twelve months ending December 31, 2005, capital
expenditures of the Group in the Natural Gas and Pipeline segment will amount to
RMB12,400 million, of which approximately RMB7,000 million will be invested in
the West-East Gas Pipeline project, the Zhongxian-Wuhan pipeline, and the second
Shaanxi-Beijing pipeline and approximately RMB5,400 million is expected to be
invested in natural gas storage infrastructure facilities and other natural gas,
crude oil and refined product transmission pipelines.


OTHERS

The Group's non segment-specific capital expenditures for the six months ended
June 30, 2004 and for the six months ended June 30, 2005 were RMB52 million and
RMB64 million respectively. These capital expenditures were mainly used for non
segment-specific equipment purchases and research and development activities.

It is estimated that the Group's non segment-specific capital expenditures for
the twelve months ending December 31, 2005 will amount to RMB1,000 million.
These capital expenditures are expected to be used for the construction of water
and power supply systems, roads and telecommunications system for the benefit of
various segments.


MATERIAL INVESTMENT

For the six months ended June 30, 2005, the Group did not hold any material
investment.


MATERIAL ACQUISITION OR DISPOSAL

Under an acquisition agreement between the Company and CNPC dated March 28,
2005, the Company has acquired the petroleum and natural gas-related refinery
and petrochemical businesses respectively 

                                       23


owned by CNPC's wholly-owned subsidiaries, Ningxia Dayuan Refinery and
Petrochemical Company Limited and Qingyang Refinery and Petrochemical Company
Limited. The Company has paid RMB9.14 million in cash as consideration for the
acquisition. Pursuant to the Listing Rules, the acquisition constitutes a
connected transaction of the Company, and the details of the transaction were
announced on March 30, 2005.


POST-BALANCE SHEET EVENTS

The Company signed an acquisition agreement ("ACQUISITION AGREEMENT") and an
equity transfer agreement ("TRANSFER AGREEMENT") with wholly owned subsidiaries
of CNPC on June 9, 2005. Under the Acquisition Agreement, the Company agreed to
acquire a 50% equity interest in ("CHINESE CHARACTERS") (Zhong You Kan Tan Kai
Fa Company Limited) ("NEWCO"), which is currently 100% held by two wholly owned
subsidiaries of CNPC, at a total consideration of approximately RMB20,741
million. The Company also agreed to enter into the Transfer Agreement at the
same time with the Acquisition Agreement pursuant to which the Company has
agreed to transfer the equity interest in PetroChina International Ltd, a wholly
owned subsidiary of the Company, to Newco for the price of RMB579 million.

As the acquisition and equity transfer constitute connected transactions of the
Company, approval of the relevant regulatory authorities and the independent
shareholders of the Company were required. The two agreements were approved by
the independent shareholders of the Company in a general meeting held on August
16, 2005.

When the Acquisition Agreement and the Transfer Agreement are completed, the
Company and China National Oil and Gas Exploration and Development Corporation
("CNODC") will each hold 50% equity interests in Newco. CNODC intends to
transfer its 50% equity interests in Newco to CNPC at nil consideration. The
Company will be entitled to appoint four out of the seven directors of Newco and
will therefore have actual control over Newco. As the Company's investment in
Newco and the transfer of equity interests in PetroChina International Ltd to
Newco are considered transactions under CNPC's common control, the pooling of
interests method is adopted for the necessary accounting treatments. The
consolidated financial statements of the Company will be re-presented on the
basis that the Company and Newco had already been consolidated.


FOREIGN EXCHANGE RATE RISK

From July 21, 2005, the PRC government has reformed the Renminbi exchange rate
regime and implemented a regulated floating exchange rate regime based on market
supply and demand with reference to a basket of currencies. However, Renminbi is
still regulated in capital projects. The exchange rates of Renminbi are affected
by domestic and international economic developments and political changes, and
supply and demand for Renminbi. Future exchange rates of Renminbi against other
currencies could vary significantly from the current exchange rates. As Renminbi
is the base currency of the Company and most of its consolidated entities, the
fluctuation of the exchange rate of Renminbi may have positive or negative
impacts on the results of operations of the Group. An appreciation of Renminbi
against United States Dollar may decrease the Group's turnover, but the cost for
acquiring imported materials and equipment may be reduced. A devaluation of
Renminbi against United States Dollar may not have a negative impact on the
Group's turnover but may increase the cost for acquiring imported materials and
equipment as well as the debt obligations denominated in foreign currencies of
the Group. The results of operations and the financial position of the Group may
also be affected by fluctuations in exchange rates of a number of other foreign
currencies against Renminbi.


COMMODITY PRICE RISK

The Group is engaged in a wide range of petroleum-related activities. The global
oil and gas market is affected by international political, economic and military
developments and global demand for and supply of oil and gas. As the prices of
Chinese crude oil and refined products are determined by reference to
international benchmark prices, fluctuations of prices of crude oil and refined
products in the international market will directly or indirectly, affect prices
of Chinese crude oil and refined products. A decrease in the prices of crude oil
and refined products could adversely affect the Group's 

                                       24


financial position. The Group has not used derivative instruments to hedge
against potential price fluctuations of crude oil and refined products.
Accordingly, the Group is exposed to general price fluctuations of oil and gas
commodities in 2005 and will remain to be so exposed thereafter.


INDUSTRY RISK

Like other oil and natural gas companies in China, the Company's operating
activities are subject to regulation and control by the PRC government in many
aspects. Regulation and control, such as by way of grant of exploration and
production licences, the imposition of industry-specific taxes and levies and
the implementation of environmental and safety standards, is expected to have an
impact on the Company's business operations. As a result, the Company may be
subject to relatively significant restrictions when implementing its business
strategy, developing and expanding its business or maximizing its profitability.
Any future changes in PRC governmental policies on the crude oil and natural gas
industry may also affect the Company's business operations.

Employee Compensation

For the six months ended June 30, 2005, the total employee compensation payable
by the Group was RMB8,048 million, being the total salaries of employees during
the reporting period. Compensation of employees is determined according to
industry practice and the actual conditions of the Group, and is based on the
principles of attracting and retaining high calibre personnel, and motivating
all staff for the realization of the best results.

The Company's senior management remuneration system links senior management
members' financial interests (including those of executive directors and
supervisors) with the Company's operating results and the market performance of
its shares. The senior management members have entered into performance
contracts with the Company. Under this system, the senior management members'
compensation has three components, namely, fixed salaries, performance bonuses
and stock appreciation rights. The variable components account for approximately
70% to 75% of the senior management officers' total potential compensation,
including approximately 0% to 25% forming the performance bonus component and
approximately 50% to 70% forming the stock appreciation rights 

                                       25


component. Variable compensation rewards are linked to the attainment of
specific performance targets, such as net profit, return on capital and cost
reduction targets. The chart below sets forth the components of the total
potential compensation for key officers.

Upon exercise of their share options, senior management staff will not receive
any shares in the Company. Instead, they will receive, by way of stock
appreciation rights, a monetary sum which is calculated on the basis of the
share price of the H shares listed on the HKSE.


Workforce Reduction Plan

During the period from 1999 to 2002, a total of 58,300 people were laid off,
which has met the target of laying off 50,000 employees originally committed by
the Company.

The Company does not have any plan for any substantial reduction of its
workforce in the next few years, but will continue to keep a strict control on
the total number of employees. Workforce required for new projects or expanded
production capacity will first be obtained by way of tapping existing resources
and making use of any spare capacity.

CONTINGENT LIABILITIES

Information on the Group's contingent liabilities as of June 30, 2005 is as
follows:


BANK AND OTHER GUARANTEES

As at June 30, 2005, the Group had contingent liabilities in respect of bank and
other guarantees and other matters arising in the ordinary course of business
from which it is anticipated that no material liabilities will arise.




                                                                      JUNE 30, 2005   DECEMBER 31, 2004
                                                                      -------------   -----------------
                                                                      (RMB MILLION)     (RMB MILLION)
                                                                      -------------     -------------
                                                                                 

Guarantees in respect of borrowings of associated companies                 211              203
                                                                            ===              ===



ENVIRONMENTAL LIABILITIES

CNPC and the Group have operated in China for many years. China has adopted
extensive environmental laws and regulations that affect the operation of the
oil and gas industry. Future environmental legislation cannot reasonably be
estimated at present, but such legislation could have a significant impact.
However, under existing legislation, except for the amounts which have already
been included in the financial statements, the management believes that there is
no liabilities for environment obligations that may have a material adverse
effect on the financial position of the Group.


LEGAL CONTINGENCIES

The Group is the named defendant in certain insignificant lawsuits as well as
the named party in other proceedings arising in the ordinary course of business.
While the outcome of such contingencies, lawsuits or other proceedings cannot be
determined at present, the management believes that any potential liabilities
which may arise will not have a material adverse effect on the financial
position of the Group.


LEASING OF LAND, ROADS AND BUILDINGS

According to the restructuring agreement entered into between the Company and
CNPC in 1999 upon the formation of the Company, CNPC has undertaken to the
Company as follows:

     o    CNPC will use its best endeavours to obtain formal land use right
          certificates to replace the entitlement certificates in relation to
          the 28,649 parcels of land which were leased or transferred to the
          Company from CNPC, within one year from August, September and October
          1999 when the relevant entitlement certificates were issued;

                                       27


     o    CNPC will complete, within one year from November 5, 1999, the
          necessary governmental procedures for the requisition of the
          collectively-owned land on which 116 service stations owned by the
          Company are located; and

     o    CNPC will obtain individual building ownership certificates in the
          name of the Company for all of the 57,482 buildings transferred to the
          Company by CNPC, before November 5, 2000.

As at June 30, 2005, CNPC obtained formal land use right certificates in
relation to 26,549 out of the above-mentioned 28,649 parcels of land, and some
building ownership certificates for the above-mentioned buildings, but did not
complete the necessary governmental procedures for the above-mentioned service
stations located on collectively-owned land. The directors of the Company
confirm that the use of and the conduct of relevant activities at the
above-mentioned parcels of land, service stations and buildings are not affected
by the fact that the relevant land use right certificates or individual building
ownership certificates have not been obtained or the fact that the relevant
governmental procedures have not yet been completed. In the management's
opinion, the outcome of the above events will not have a material adverse effect
on the results of operations or the financial position of the Group.


GROUP INSURANCE

Except for limited insurance coverage for vehicles and certain assets subject to
significant operating risks, the Group does not carry any other insurance for
its property, facilities or equipment for its business operations. In addition,
the Group does not carry any third-party liability insurance against claims
relating to personal injury, property and environmental damages or business
interruption insurance since such insurance coverages are not customary in
China. While the effect of under-insurance on future incidents cannot be
reasonably assessed at present, the management believes that it may have a
material impact on the operating results but will not have a material adverse
effect on the financial position of the Group.


OTHERS

In December 2003, a gas blow-out incident occurred at one of the gas wells of
the Group. The blow-out caused the leakage of a large quantity of sulfurated
hydrogen, causing injuries and deaths to many residents living in the
surrounding area. As a result of an investigation conducted by the PRC
government, CNPC, which provided the Company with drilling services for the
well, was held liable for this blow-out. The incident has not had, and the
Company does not believe it will have, a material adverse effect on the results
of operations and financial position of the Group.


MARKET REVIEW

Crude Oil Market Review

During the first half of 2005, international crude oil prices continued to rise
due to high demand and tight supply. Despite various controls and influences,
the oil market and prices were subject to significant fluctuations. The
international oil prices hit the record high repeatedly. WTI, Brent and Minas
crude oil in the first half of the year averaged US$51.49, US$49.65 and US$50.87
per barrel respectively, representing an increase of US$14.68, US$15.99 and
US$17.73 per barrel respectively from the first half of 2004. Domestic crude oil
prices rose accordingly under the impact of international oil prices. The
average realized price was higher than that of the first half of 2004.

Domestic import of crude oil continued to grow during the first half of 2005.
Domestic net crude oil import surged 3.2% to 59.81 million tons compared with
the corresponding period of last year. Domestic crude oil output and the amount
of crude oil processed reached 90.46 million tons and 134 million tons
respectively.

                                       28


Refined Products Market Review

During the first half of 2005, although the PRC government strengthened control
on the domestic macro-economy, demand for refined products still remained
relatively high. In general, resources were tight and market prices continued to
rise and hit new historical highs repeatedly. From January to June, nominal
consumption increased 5.56% to 79.88 million tons compared with the same period
of last year. By the end of June 2005, the refined products inventory held by
the Company and Sinopec dropped to 7.34 million tons, a reduction of 0.8 million
tons compared with the corresponding period of last year.

The PRC government has made appropriate adjustments to the prices of domestic
refined products during the first half of 2005. However, under the impact of
international oil prices, the average benchmark prices of gasoline and diesel
were still higher than the level during the corresponding period of last year.


Chemical Products Market Review

During the first half of 2005, as international oil prices remained high and
there was a slow-down in the growth of the domestic economy, the operating
results for the petrochemical industry were increasingly divergent. On the one
hand, the upstream raw materials industry maintained a high level of profits due
to few new production start-ups; on the other hand, the downstream processing
industry recorded a significant slowdown in operating results due to high costs.
In general, the petrochemical industry during the first half of 2005 featured a
period from an increase in growth to a slight slowdown in growth.

It is estimated that in the second half of the year, with the restructuring of
the macro-economy and the implementation of measures relating to restrictions of
investment, the growth of the economy will be slowed down. However, a growth
rate of approximately 9% will be maintained and the growth in demand for
petrochemical products will be greater than the growth of gross domestic
product. The fourth quarter of 2005 will be a low season and demand will be
lower than that during the first half of 2005. With some new petrochemical
facilities in China commencing production, supplies will increase significantly.
As a result, it is estimated that petrochemical products will gradually be
oversupplied for the second half of 2005. It is inevitable that prices of
petrochemical products will be unstable and lower and the overall prices will be
lower than those in the first half of 2005.
