The U.S. Treasury Department’s Office of Foreign Assets Control sanctioned 10 individuals and entities for helping Iran’s Ministry of Defense and Armed Forces Logistics procure weapons, electronic components and other military-related goods. The targets include networks operating in Iran, China, Hong Kong and Pakistan, with related entities in Saudi Arabia and Türkiye. Treasury said the measures are part of Operation Economic Outcast, the Trump administration’s broader effort to isolate Iran economically, raise costs for its procurement networks and pressure Tehran to negotiate an end to the U.S.-Iran war that began in February. The department said the action is intended to hinder Iran’s ability to rebuild its weapons programs. Treasury Secretary Scott Bessent said the United States would continue identifying and isolating those supporting Iran’s military and security apparatus. The designations come as the rial fell below 2.5 million per dollar, surpassing its previous low of 2.2 million reached on Sept. 2, while renewed U.S.-Iran diplomacy remains uncertain.
