Company Announcement

                                [COMPANY LOGO]

                            2006 Business Strategy

In line with its policy of keeping the market informed of its activities, the
Company announces a summary of its business strategy and development plan for
the year 2006.

This announcement contains statements that are not historical facts, including
statements about beliefs and expectations of the directors of the Company on
the Company and its development and future plans. These forward-looking
statements reflect the directors' current views with respect to future events
and are not a guarantee of future performance, and therefore shareholders and
potential investors should not place undue reliance on them. The directors of
the Company undertake no obligation to update or revise publicly any of these
forward-looking statements, whether in light of new information, future events
or otherwise. Forward-looking statements involve inherent risks and
uncertainties. Shareholders and potential investors are cautioned that a
number of factors could cause actual results to differ materially from those
contained in any forward-looking statement. Such factors include, but are not
limited to, changes in the Chinese economic, political and social conditions
and government policies and in the oil and gas industry.

In line with its policy of keeping the market informed of its activities,
CNOOC Limited (the "Company") announces a summary of its business strategy and
development plan for the year 2006.

The Company's total budgeted net production volume in 2006 is approximately
168-170 million BOE (barrels of oil equivalent), approximately a 9%
year-on-year increase over the estimated 153-157 million BOE in 2005. Net
production offshore China is estimated to be 148-149 million BOE in 2006. The
Company's overseas output is expected to be enhanced by the North West Shelf
Project in Australia, which is scheduled to supply gas to Guangdong LNG
terminal in the first half of 2006. With this project, the Company's net
entitlement overseas is expected to reach approximately 20-21 million BOE
(with reference of WTI US$55.3/barrel (or approximately HK$431.34/barrel),
"WTI" is a standard oil price for grades of crude oil).

During the year, ten projects offshore China are expected to come on stream,
two of which are ready for production. Overall, for 2006 and 2007, it is
expected that 16 projects will be completed. 

On the exploration front, the Company plans to conduct more drilling, seismic
acquisition activities offshore China, particularly in Bohai Bay and the South
China Sea, in order to explore oil and gas potentials. Overseas exploration
activities will be further strengthened. The exploration budget is estimated
to increase 72% to reach the level of US$455 million (or approximately
HK$3,549 million) and the reserve replacement ratio is targeted to be more
than 100% in 2006.

At the same time, the Company expects to spend US$2.59 billion (or
approximately HK$20.2 billion) in development, a 30% year-on-year increase. In
total, the Company's 2006 capital expenditure is budgeted at approximately
US$3.06 billion (or approximately HK$23.87 billion), 35% up from last year's
figure.

With the commencement of new gas projects and Guangdong LNG terminal of China
National Offshore Oil Corporation, the parent company of the Company, it is
believed that the Company will further strengthen its leading position in gas
business in costal China.
