May 29 (Reuters) - Chevron ( CVX ) shareholders on

Wednesday voted to re-elect all 12 sitting directors to its

board, in a sign of support for the oil major.

CEO Michael Wirth said the company is moving ahead on the

U.S. Federal Trade Commission's review of its proposed buyout of

oil producer Hess Corp ( HES ) in the coming weeks.

The $53 billion deal requires U.S. regulatory approval and

faces a challenge by Exxon Mobil ( XOM ) and CNOOC,

which claim they have pre-emption rights to any sale of Hess'

Guyana assets.
