According to the official, the Treasury Department is now focused on developing new sanctions against the Russian Federation specifics of which will be announced in the near future.
Late July 2017, the U.S. Senate passed the new sanctions bill against Russia overwhelmingly and sent it to Trump for signature. Russia in response restricted U.S. diplomatic missions' access to several facilities and demanded to shorten the staff of the mission by 755 people by Sept. 1.
Trump signed the new bill on Russia sanctions on Aug. 2, but in a signing statement, he said he sees serious flaws in this document, although signs it for the sake of the national unity.
On Nov. 29, 2017, the U.S. boosted sanctions against the energy and banking sectors of the Russian economy. Restrictions were imposed on the terms of financing of sanctioned Russian companies by American companies and individuals, as well as from the territory of the United States.
