Rosneft President and Chairman of the Management Board Igor Sechin attends a meeting of Russia's President Vladimir Putin and his Chinese counterpart Xi Jinping at the Kremlin in Moscow in this March 22, 2013 file photo. The United States on April 28, 2014 imposed sanctions against seven Russian government officials and 17 companies linked to Russian President Vladimir Putin in its latest action to punish Moscow for its intervention in Ukraine. The White House said the seven Russians, who include Sechin, head of Russia's major oil company Rosneft and a close ally of Putin, are now subject to a freeze on any assets they hold in the United States and a ban on U.S. travel.
