U.S. will not give Exxon permission to drill in Russia

The United States will not make an exception for American companies, including oil major Exxon Mobil Corp, seeking to drill in areas prohibited by U.S. sanctions on Russia, Treasury Secretary Steven Mnuchin said on Friday.

The unusually direct statement served to clarify that the United States would maintain a tough stance on sanctions against Moscow.

"In consultation with President Donald J. Trump, the Treasury Department will not be issuing waivers to U.S. companies, including Exxon, authorizing drilling prohibited by current Russian sanctions," Mnuchin said in a statement.

The United States and European Union imposed economic sanctions on Russia over its annexation of the Crimea region in 2014 and its role in the conflict in eastern Ukraine. The sanctions forced Exxon, the world's largest publicly traded oil producer, to wind down drilling in Russia's Arctic in 2014.

"We understand the statement today by Secretary Mnuchin in consultation with President Trump," Exxon spokesman Alan Jeffers said.
