Agreement with CNPC on 18 March 2007, pursuant to which, the Company will

percentage ratio exceeds 2.5%, the disposal constitutes a connected transaction
of the Company subject to reporting, announcement and independent shareholders'
approval requirements under Chapter 14A of the Listing Rules.

A circular containing, among other things, details of the Disposal, a letter

1.   BACKGROUND INFORMATION AND LISTING RULES IMPLICATION

     On 18 March 2007, the Company entered into the Equity Transfer Agreement
     with CNPC to dispose, subject to certain pre-conditions as set out below,
     its entire equity interest in China United Oil, representing 70% of the
     entire registered capital of China United Oil as at the date of this
     announcement. Following the Disposal, the Company will cease to hold any
     equity interest in China United Oil.

     CNPC is a promoter and substantial shareholder of the Company, holding
     approximately 88.21% of the issued share capital of the Company as at the
     date of this announcement. CNPC is therefore a connected person of the
     Company and accordingly the Disposal constitutes a connected transaction
     under Chapter 14A of the Listing Rules.

     As the highest applicable percentage ratio, being the revenue ratio, has
     exceeded 2.5%, the Disposal constitutes a connected transaction subject to
     the reporting, announcement and independent shareholders' approval
     requirements under Chapter 14A of the Listing Rules. CNPC and its
     associates (as defined under the Listing Rules) will be required to abstain
     from voting in respect of the resolution on the Disposal.

     A Board meeting was convened on 18 March 2007 to approve the Equity
     Transfer Agreement. The Board approval is condition upon, inter alia, the
     Independent Shareholders' approval. The Directors, including the
     independent non-executive directors of the Company, are of the view that
     the transaction is entered into after arm's length negotiations, the
     consideration payable by CNPC and the other terms of the Disposal are fair
     and reasonable and are in the interest of the Shareholders as a whole.

                                  completion.

     Basis of Consideration

     The consideration is approximately RMB1.01 billion, which has been
     determined after arm's length negotiations, with reference to and is
     approximately equivalent to 70% of the appraisal value of China United Oil
     as at 31 December 2006 of RMB1.44 billion. The above valuation was
     conducted based on a cost-base method by Beijing China Enterprise Appraisal
     Co., Ltd, a PRC qualified asset valuer which is independent of the Group.

     The following financial information was derived from the audited accounts
     of China United Oil prepared under PRC GAAP.




                                                        Year ended 31 December
                                                           2005           2006
                                                     (RMB$,000)     (RMB$,000)
                                                              

     Net  profit  (loss)  before  taxes              417,691.04     447,391.95
     Net  profit  (loss)  after  taxes               263,213.16     273,052.37


     The net asset value of China United Oil as of 31 December 2006 was
     approximately RMB1.275 million, based on which, the Group will be able to
     recognize a gain of RMB117 million. The net proceeds of the Disposal are
     intended to be used for further development of the Company's core
     businesses.

3.   REASONS AND BENEFITS FOR THE CONNECTED TRANSACTION

     Although the Company holds 70% of the equity interests in China United Oil,
     China United Oil is equity accounted for by the Company as the Company has
     little or no control over the board and management of China United Oil. The
     articles of association of China United Oil states that unanimous
     shareholder approval is required for major corporate actions, including
     increasing or decreasing its registered share capital, allocation of
     profits and losses and changing its corporate structure. Furthermore,
     representatives from the Company and Sinochem must be present for China
     United Oil to convene any board meeting. As a result, despite holding 70%
     of the equity interests in China United Oil, the Company has no actual
     control over the running of China United Oil. As the Company is unable to
     unilaterally decide on the strategy and direction of China United Oil,
     China United Oil could in the future potentially grow and develop along a
     direction that is inconsistent with the Company's overall strategy.

     Furthermore, the Company has gradually been transferring its import and
     export businesses of crude oil and refined oil to PetroChina International,
     a wholly-owned subsidiary of the Company incorporated under the laws of PRC
     in 2002. As the Company is able to exercise total control over PetroChina
     International, the Company intends to conduct most of its import, export
     and related international trade businesses through PetroChina International
     in the future.

     Based on the foregoing, the Directors, including the independent
     non-executive Directors, are of the view that it is in the interests of the
     shareholders of the Company that China United Oil is disposed of.
