The U.S. Treasury said Wednesday it has notified Congress of its intent to terminate sanctions on Russian aluminum giant Rusal after divestment by Oleg Deripaska, the Russian tycoon. Treasury said that Deripaska will remain sanctioned, however, with his property blocked. Unless Congress blocks the action, sanctions will be removed on Rusal, En+ Group and JSC EuroSibEnergo, Treasury said. "These companies have committed to significantly diminish Deripaska's ownership and sever his control," said Treasury Secretary Steven Mnuchin.
