Russia can’t immediately cut oil production, the head of Russia’s state oil company said Tuesday after a meeting with senior officials from other major oil producers. Igor Sechin said Rosneft, the world’s largest listed oil company by output, could postpone some capital-intensive projects, which would have some impact on oil supply. But he said Russia, unlike members of the Organization of the Petroleum Exporting Countries, couldn’t cut production immediately. “The current price level isn’t critical for us,” he said in a company statement. Mr. Sechin’s comments come ahead of an OPEC meeting on Thursday where officials will discuss oil policy amid recently falling oil prices. Mr. Sechin, a close ally of President Vladimir Putin, met with senior officials from Saudi Arabia, Venezuela and Mexico on Tuesday
