Nexen said Tuesday the Committee on Foreign Investment in the United States has now given its approval, clearing the way to close China's biggest overseas energy deal in the week of Feb. 25.
The Committee reviews takeovers by foreign-owned companies for national security implications. CNOOC's acquisition of the Canadian company falls under U.S. jurisdiction because of Nexen's Gulf of Mexico oil and gas operations.
Britain and the European Union have also given their go ahead for the Nexen takeover.
