"The United States imposes sanctions on Russian persons (individuals and entities) for aggression against Ukraine, election interference, malicious cyber activity, human rights violations, weapons proliferation, and other activities. U.S. sanctions regimes against Russia have increased in complexity and scope with enactment of the Countering Russian Influence in Europe and Eurasia Act of 2017 (CRIEEA; P.L. 115-44, Countering America's Adversaries Through Sanctions Act, Title II; 22 U.S.C. 9501 et seq.). Sanctions against Russian persons can include blocking U.S.-based assets; prohibiting U.S. persons from engaging in transactions related to those assets; prohibiting certain, and in some cases all, U.S. transactions; and denying entry into the United States. The United States also tightly controls exports to Russia's energy and defense sectors and restricts exports where the end-use might have military application. Each rationale for imposing sanctions and the sanctions tools used, however, have their own nuances."
