The United States froze assets and imposed visa bans on seven powerful Russians close to President Vladimir Putin on April 28 and also sanctioned 17 Russian companies in reprisal for Moscow's actions in Ukraine. President Barack Obama said the moves, which add to measures taken when Russia annexed Crimea last month, were to stop Putin fomenting rebellion in eastern Ukraine - an allegation Moscow denies. A Russian diplomat voiced "disgust" at the White House.
