The U.S. Department of the Treasury posted on 28 September 2023 an announcement titled "Treasury Designates Entities and Individual Exacerbating Sudan's Instability."
New US sanctions target a Sudan-based information technology and security company that has been used as a procurement channel for the Rapid Support Forces (RSF) and a Russia-based military supply company that arranges procurement of parts and supplies purchased by the RSF. The Treasury Department also sanctioned Ali Karti, foreign minister during the Omar al-Bashir government and now the leader of the Sudanese Islamic Movement.
