Overview

• The U.S. formally determined on April 24, 2025, that Sudan's military used chemical weapons during its civil war in 2024, invoking the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991.
• Sanctions, including restrictions on U.S. exports and government credit, are scheduled to take effect around June 6 following Congressional notification on May 22.
• The State Department has called on Sudan to cease chemical weapons use and fulfill its obligations under the Chemical Weapons Convention, an international treaty it has signed.
• Sudan's government has rejected the U.S. findings, describing them as a 'deliberate distortion of facts' and denying any use of chemical weapons.
• Experts warn that the sanctions will likely exacerbate civilian suffering in a country already grappling with one of the world's worst humanitarian crises, with over 13 million displaced since the conflict began in April 2023.
