ANNOUNCEMENT

     The Stock Exchange of Hong Kong Limited takes no responsibility for the
     contents of this announcement, makes no representation as to its accuracy
     or completeness and expressly disclaims any liability whatsoever for any
     loss howsoever arising from or in reliance upon the whole or any part of
     the contents of this announcement.

     CNOOC LIMITED
     (Incorporated in Hong Kong with limited liability under the
     Companies Ordinance)

     PROPOSAL FOR SUBDIVISION OF SHARES

     The Company will propose to its shareholders that each of the existing
     issued and unissued shares of HK$0.10 each in the share capital of the
     Company be subdivided into five shares of HK$0.02 each. The board lot for
     trading of Shares in the Company will thereafter be changed to 1,000
     shares of HK$0.02 each.

     A circular containing, among other things, details of the Share
     Subdivision and the trading arrangement in respect of the Subdivided
     Shares together with a notice to convene the EGM will be issued to the
     shareholders of the Company as soon as practicable.

     SHARE SUBDIVISION

     CNOOC Limited (the "Company") will put to its shareholders a proposal
     that each of the existing issued and unissued shares of HK$0.10 each in
     the capital of the Company ("Share") be subdivided ("Share
     Subdividision") into five shares of HK$0.02 each ("Subdivided Share").
     Upon completion of the Share Subdivision and the change of the board lot
     size as referred to below, the monetary value of each board lot of the
     Subdivided Shares will be less than the value of the existing board lot
     of Shares. In view of the prevailing market condition, the board of
     directors of the Company considers that the Share Subdivision may improve
     liquidity of the Subdivided Shares and enable the Company to attract more
     investors and widen its shareholder base.

     As at the date of this announcement, the authorized share capital of the
     Company is HK$15,000,000,000.00 which is divided into 150,000,000,000
     Shares, of which 8,214,165,655 Shares are in issue. Immediately upon
     completion of the Share Subdivision, the authorized share capital of the
     Company will be HK$15,000,000,000.00 comprising 750,000,000,000
     Subdivided Shares, of which 41,070,828,275 Subdivided Shares will be in
     issue and fully paid assuming that no further Shares are issued or
     repurchased prior to the completion of the Share Subdivision. The
     Subdivided Shares will rank pari passu in all respects with the Shares in
     issue prior to the Share Subdivision (but their nominal value will be
     different) and the rights attaching to the Subdivided Shares will not be
     affected by the Share Subdivision.

     The Company has securities in the form of American Depositary Receipts
     ("ADRs") listed on the New York Stock Exchange, Inc. Each ADR represents
     20 Shares. It is also proposed that, upon the Share Subdivision becoming
     effective, the ratio of the outstanding ADRs be changed such that one
     ADR, which currently represents 20 Shares, will represent 100 Subdivided
     Shares. Further details on the proposed change to the Company's ADRs will
     be provided to the Company's ADR holders as soon as practicable.

     CHANGE OF BOARD LOT SIZE

     At present, the Shares are traded in board lots of 500 Shares and upon
     fulfillment of the conditions of the Share Subdivision, the board lot
     will be increased and will be 1,000 Subdivided Shares.

     CONDITIONS OF THE SHARE SUBDIVISION

     The Share Subdivision is conditional upon, inter alia:





     (a) the passing of an ordinary resolution by shareholders of the Company
     at an extraordinary general meeting ("EGM") of the Company; and

     (b) the Listing Committee of The Stock Exchange of Hong Kong Limited (the
     "Stock Exchange") granting the listing of and permission to deal in the
     Subdivided Shares and the Subdivided Shares to be issued pursuant to the
     exercise of options in accordance with the Company's share option
     schemes.

     Apart from the payment of the expenses for the Share Subdivision,
     implementation of the Share Subdivision will not, of itself, alter the
     underlying assets, business operations, and management or financial
     position of the Company or the proportional interests of its shareholders
     in the Company. The board of directors of the Company believes that the
     Share Subdivision will not have a material adverse effect on the
     financial position of the Company and its subsidiaries.

     ARRANGEMENT ON ODD LOT TRADING

     In order to facilitate the trading of odd lots of Subdivided Shares as a
     result of the Share Subdivision and the change of the board lot size, the
     Company will appoint a broker (the "Agent") to act as agent in providing
     a "matching service" to those shareholders who wish to top-up or sell
     their holdings of odd lots of the Subdivided Shares.

     The Agent, details of which will be provided in the circular to
     shareholders referred to below, will provide the service to match the
     sale and purchase of odd lots of Subdivided Shares during the period from
     17 March 2004 to 26 April 2004, both dates inclusive. Holders of
     Subdivided Shares in odd lots who wish to take advantage of this facility
     either to dispose of or top-up their odd lots to a board lot of 1,000
     Subdivided Shares may, directly or through their brokers, contact the
     Agent during such period. Shareholders should note that successful
     matching of the sale and purchase of odd lots of Subdivided Shares is not
     guaranteed and will depend on there being adequate amounts of odd lots of
     Subdivided Shares available for such matching.

     Shareholders are recommended to consult their professional advisers if
     they are in any doubt about the matching facility described
     above.
