Executive Order 13883
Administration of Proliferation Sanctions and Amendment of Executive Order 12851
This executive order delegates presidential authorities under the Chemical and Biological Weapons Control and Warfare Elimination Act to the Secretary of the Treasury, imposing sanctions on countries determined to have used chemical or biological weapons. It requires Treasury to oppose international financial institution loans and prohibit U.S. bank loans to sanctioned governments, with exceptions for food and agricultural purchases. The order also amends Executive Order 12851 to formally delegate these authorities from the President to the Treasury Secretary.
