Russia: The Navalny Poisoning, Chemical Weapons Use, and U.S. Sanctions [July 12, 2021] [open pdf - 515KB]
From the Document: "On March 2, 2021, U.S. Secretary of State Antony Blinken determined that in August 2020 the Russian government used a chemical weapon in an attack on opposition figure and anticorruption activist Alexei Navalny in violation of international law and against one of its own nationals. This finding triggered requirements under the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (CBW Act; title III, P.L. 102-182; 22 U.S.C. 5601 et seq.). The Biden Administration imposed an initial round of sanctions, as required by the CBW Act. The CBW Act requires the President to impose economic and diplomatic measures that could cut off foreign aid, arms sales, and export licenses for controlled goods, services, and technology, and ratchet up in intensity if certain conditions are not met within 90 days."
