"The United States has long supported Ukraine's pro-Western orientation and reform efforts. It supports the restoration of Ukraine's territorial integrity, including with respect to Crimea, as well as implementation of the Minsk agreements that would establish a cease-fire and conflict settlement in eastern Ukraine. In 2014, the United States, in coordination with the European Union and others, imposed sanctions on Russia for its actions in Ukraine. The United States is a leading contributor of foreign assistance to Ukraine, including over $300 million a year since FY2015 in nonmilitary, nonhumanitarian assistance. The United States also provides substantial military assistance to Ukraine, including via a newly established Ukraine Security Assistance Initiative that provides 'appropriate security assistance and intelligence support' to help Ukraine defend against aggression and support its sovereignty and territorial integrity. [...] The U.S. Congress has actively participated in efforts to address the Ukraine conflict since its onset. Many Members have condemned Russia's annexation of Crimea and support for separatists in eastern Ukraine and pushed to impose and retain sanctions against Russia for its actions. Congress has also supported substantial economic and security assistance for Ukraine. Key legislation includes the Support for the Sovereignty, Integrity, Democracy, and Economic Stability of Ukraine Act of 2014 (P.L. 113-95), the Ukraine Freedom Support Act (P.L. 113-272), and the Countering Russian Influence in Europe and Eurasia Act of 2017 (P.L. 115-44, Title II)."
