The United States supports Ukraine’s sovereignty and territorial integrity within its internationally recognized borders, while actively promoting the continuation and consolidation of domestic reforms. Since Ukraine’s independence, and especially after Russia’s 2014 invasion, Ukraine has been a leading recipient of U.S. foreign, humanitarian, and military aid in Europe and Eurasia. Nonmilitary, non-humanitarian assistance totaled an average of $320 million a year from FY2015 to FY2018. The United States provides substantial military assistance to Ukraine, including via the Ukraine Security Assistance Initiative, which provides “appropriate security assistance and intelligence support” to help Ukraine defend its sovereignty and territorial integrity. Since 2014, many Members of Congress have condemned Russia’s invasion of Ukraine, promoted sanctions against Russia for its actions, and supported increased economic and security aid to Ukraine. Key legislation includes the Support for the Sovereignty, Integrity, Democracy, and Economic Stability of Ukraine Act of 2014 (SSIDES; P.L. 113-95; 22 U.S.C. 8901 et seq.), the Ukraine Freedom Support Act of 2014 (UFSA; P.L. 113-272; 22 U.S.C. 8921 et seq.), and the Countering Russian Influence in Europe and Eurasia Act of 2017 (CRIEEA; Title II of P.L. 115-44, Countering America’s Adversaries Through Sanctions Act [CAATSA]; 22 U.S.C. 9501 et seq.).
