The US Department of the Treasury’s Office of Foreign Assets Control (OFAC) has announced economic sanctions against six “entities” (businesses and individuals) that it accuses of supporting Iran’s Islamic Revolutionary Guard Corps (IRGC). Mahan Air is a privately-owned Iranian airline which OFAC accuses of being “the IRGC’s airline of choice for moving weapons, military personnel, and equipment,” including drones. OFAC says that China‑based Tang Xin, who is the managing director of Shanghai Wings Logistics Company, has coordinated travel for Mahan Air. OFAC says that the sanctions are authorized under Executive Order 13224, as amended. It blocks the property and interests of designated entities and prohibits US citizens from transacting with them without permission.
