WASHINGTON _ The Trump administration announced significant new sanctions on Tuesday targeting Rosneft, Russia's largest oil company, for helping Venezuelan leader Nicolas Maduro circumvent U.S. sanctions.
The Treasury Department blocked all U.S. assets of Rosneft�s subsidiary, Rosneft Trading S.A., and its director, Didier Casimiro.
But the sanctions will also affect "anyone engaging in activity" with the Russian company, senior administration officials said, characterizing Rosneft as the "primary culprit" of a campaign to evade Washington's pressure on the Maduro regime.
