SHEL Shell Plc

LONDON--Royal Dutch Shell PLC (RDSA.LN) and China National Offshore Oil Corporation announced late Tuesday that they have signed a global strategic alliance agreement that reconfirms both parties' commitment to the existing strategic partnership in China and around the world.

Under the agreement, the companies will commit to exploring potential cooperation opportunities in upstream, midstream and downstream, they said in a joint statement.

Shell and CNOOC have enjoyed an excellent partnership in and outside China in both upstream and downstream projects including offshore Yinggehai off Hainan Island and a successful petrochemicals joint venture in Huizhou, Guangdong province.

The parties are also working together in liquefied natural gas projects and upstream deepwater projects including in Gabon and Brazil among others.
