Unocal Corporation
In June 2005, a CNOOC Group company (NYSE and Hong Kong-listed public company CNOOC limited) made an $18.5 billion cash offer for American oil company Unocal Corporation, topping an earlier bid by ChevronTexaco. Unocal's oil interests in Central Asia were considered a strategic fit for the company. On July 20, 2005, Unocal announced that it had accepted an buyout offer from ChevronTexaco for $17.1 billion, which was submitted to Unocal stockholders on August 10. On August 2 CNOOC Limited announced that it had withdrawn its bid, citing political tensions in the United States.
