VOLUNTARY ANNOUNCEMENT

 

This announcement is made by CNOOC Limited (the “Company”) on a voluntary basis.

 

The Company refers to the Penglai 19-3 oilfield oil spill accidents which occurred in June 2011 (the “Oil Spill Accidents”). References are made to relevant information regarding the Oil Spill Accidents disclosed under the paragraph headed “Contingencies” in the annual reports and/or interim reports issued in or after 2012.

 

The Company announces that it has received a Notice Calling for Responses from the Qingdao Maritime Court of the People’s Republic of China on 10 August 2015 for a public interest action filed by China Biodiversity Conservation and Green Development Foundation (the “Plaintiff”) in relation to the Oil Spill Accidents (the “Claim”). The Claim is lodged against ConocoPhillips China Inc. (a subsidiary of a US based oil company, ConocoPhillips) and CNOOC China Limited (a wholly-owned subsidiary of the Company) (together, the “Defendants”).

 

The Plaintiff requires the Defendants to: (1) restore the ecological environment in the Bohai Bay as damaged by the Oil Spill Accidents so that the environment will be brought back to its original condition before the accidents occurred; (2) if the Defendants fail to set up and implement a scientific plan to restore the ecological environment in the Bohai Bay within three months after a court judgment is granted in favor of the Plaintiff, establish a fund specifically for the restoration of the ecological environment in the Bohai Bay . Such fund shall be supervised by a professional public welfare foundation and the total amount of such fund shall be fixed based on the estimated costs for restoring the ecological environment in the Bohai Bay as determined by a professional institution; and (3) bear all litigation costs incurred by the Plaintiff in connection with the Claim.

 

CNOOC China Limited has engaged PRC lawyers in relation to the Claim and intends to defend the Claim vigorously.

 
 

 

In the meantime, holders of shares and securities and potential investors of the Company should exercise caution when dealing in the shares of the Company.

 

If there is any significant development in relation to the Claim, the Company will issue further announcements as and when required under the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited.
