     The basis and explanations for the reconciliation items between the
Company's financial


                                        7



statements prepared under PRC GAAP and that under IFRS are as follows:

     Note (1): Oil and gas properties are depleted using unit of production
     method under IFRS but using straight-line method under PRC GAAP.

     Note (2): The assets and liabilities transferred to the Company by CNPC
     during the restructuring of CNPC in 1999 were appraised as at 30 June 1999
     by China Enterprise Appraisals Co., Ltd*. All revaluation results were
     recorded under PRC GAAP, but under IFRS, only fixed assets were measured at
     revalued amounts, thus the revaluation results of assets other than fixed
     assets were not recorded.

     Note (3): Since the fixed assets were measured at revalued amounts under
     IFRS, revaluations are required to be performed by independent qualified
     valuers periodically. In order to meet this requirement under IFRS, as at
     30 September 2003, a revaluation of the Company and its subsidiaries'
     refinery and chemical production facilities was undertaken by China United
     Assets Appraiser Co., Ltd*, a firm of independent valuers registered in the
     PRC, on a depreciated replacement cost basis. The revaluation results were
     recorded under IFRS, but under PRC GAAP, fixed assets were measured at
     historical cost, thus the revaluation results were not recorded.

     Note (4): Under PRC GAAP, the impairment losses recognized for long-term
     assets such as fixed assets, oil and gas properties, intangible assets and
     long-term investments in previous periods can not be reversed. But under
     IFRS, if there is any indication that the factors which caused the
     impairment losses may have changed, and the recoverable amounts of the
     long-term assets exceed the carrying amounts, the impairment losses
     recognized in previous periods can be reversed.

     Note (5): The Company acquired 100% interests in Ningxia Dayuan Refinery
     and Petrochemical Company Limited* ("DAYUAN PETROCHEMICAL AND REFINERY")
     and Qingyang Refinery and Petrochemical Company Limited* ("QINGYANG
     PETROCHEMICAL AND REFINERY") from CNPC. The balance sheet as of 1 January
     2005 and the income statement for the year 2005 have been restated as if
     the operations of the Company, Dayan Petrochemical and Refinery and
     Qingyang Petrochemical and Refinery have always been combined in previous
     accounting years, but the comparative information of 2004 is not
     retrospectively adjusted. Under IFRS, this acquisition was recorded in a
     manner similar to uniting of interests as if the operations of the Company
     and these refinery and petrochemical businesses have always been combined
     in the previous accounting years.

     Note (6): The shareholders of the Company approved the acquisition in
     August 2005

     pursuant to which the Company agreed to acquire 50% interests in CNPC
     Exploration and Development Company Limited* (CHINESE CHARACTER) ("CNPC
     E&D"). The consolidation reference date for this transaction was 31
     December 2005, the date that the Company obtained de facto control of CNPC
     E&D. The balance sheet as of 1 January 2005 and the income statement for
     the year 2005 have been restated as if the operations of the Company and
     CNPC E&D have always been combined in previous accounting years, but the
     comparative statistics of 2004 is not retrospectively adjusted. Under IFRS,
     this acquisition was recorded in a manner similar to uniting of interests
     as if the operations of the Company and CNPC E&D have always been combined
     in the previous accounting years.

     reconciliation items (1) to (6) above and other differences between
     accounting standards.
