A week after snagging a top spot in quarterly league transactional tables, White & Case has been tapped for some big oil work in Russia, according to TASS, a Kremlin-owned news service.

Russian government-controlled NK Rosneft OAO has enlisted the firm to advise on its planned sale of a less than 20 percent stake in the energy giant worth $7.5 billion. Bloomberg reports that the engagement by White & Case follows a recent trend of Russian companies turning to U.S. law firms at a time when Western sanctions are hampering deals. (Many big firms with offices in Russia have scaled back their operations following the country’s crisis with neighboring Ukraine.)
