A Rosneft oil company logo sits on display on a plaque at the entrance to the headquarters of OAO Rosneft, the state-run producer which pumps 40 percent of Russia’s oil, in Moscow, Russia, on Monday, Aug. 18, 2014. Rosneft asked the state for as much as 1.5 trillion rubles ($42 billion) of aid, a government official said, signaling a U.S. ban on long-term loans to Russia’s largest company is starting to bite.
