On 2 August 2017, President Donald Trump signed H.R. 3364, the Countering America’s Adversaries Through Sanctions Act, which included provisions related to sanctions on Russia, Iran, and North Korea. The law, specifically in sections 253 and 257, reaffirmed the United States’ policy of not recognizing territorial changes effected by force, including Russia’s illegal annexation of Crimea. These sections explicitly stated that the U.S. “does not recognize territorial changes effected by force” and will “never recognize the illegal annexation of Crimea by the Government of the Russian Federation or the separation of any portion of Ukrainian territory through the use of military force.”
