And now, on Wednesday, the Treasury Department named 21 entities and 17 individuals involved in networks that have helped procure technology for advanced surface-to-air missile systems and the illegal purchase of a U.S.-manufactured helicopter. The sanctions include penalties on a network that works out of Iran, Hong Kong, and China for sourcing U.S.-origin, dual-use electronics for an Iranian-controlled firm that produces equipment for the Iranian military. In addition, the Treasury Department is sanctioning a group operating out of Iran, Germany, Turkey, Portugal, and Uruguay that procured a U.S.-origin helicopter, for the Iranian military. The Treasury Department worked with the State Department, the Department of Homeland Security, and Federal Bureau of Investigation to gather intelligence for these sanctions. It remains unclear how Tehran will respond to the new rounds of sanctions.
