The United States prolonged sanctions against Russia because of the ongoing aggression in Donbas and the annexation of Crimea. The U.S. Department of the Treasury reported that on the website on December 20.
Seven individuals and a dozen of entities, as well as two Russian ships fell under the sanctions; specifically, assets of these people and companies will be frozen in the U.S., and American resident companies will be banned from having any contacts with their Russian colleagues.
'Today’s action is in response to Russia’s unlawful occupation of Crimea and continued aggression in Ukraine,' said John E. Smith, Acting OFAC Director. 'These targeted sanctions aim to maintain pressure on Russia by sustaining the costs of its occupation of Crimea and disrupting the activities of those who support the violence and instability in Ukraine.'
