MOSCOW (Reuters) - Glenn Waller, the head of ExxonMobil operations in Russia, said on Tuesday that the company will return to its joint oil project with Rosneft in the Russian Arctic once sanctions against Moscow are lifted.

The oil major had to withdrew from the drilling project with Rosneft in 2014 when the West imposed sanctions against Moscow for its role in the Ukrainian crisis.
