CNOOC buys two blocks in oil auction

Energy reform in Mexico opens market for first time in the nation for almost 80 years

CNOOC, China's largest offshore oil and natural gas producer, has strengthened its investment in Mexico's energy sector by buying two deepwater oil blocks at auction.

China National Offshore Oil Corp has won two of the 10 blocks on offer, one of them just 6.5 kilometers from the maritime border with the US, with bids that far outstripped the minimum required, according to the State-owned company.
