The US sanctioned dozens of firms and people supporting Iran’s ballistic missile and drone manufacturing industry across countries in Asia and the Middle East as part of the Trump administration’s “maximum pressure” campaign against Tehran.

The Treasury Department announced sanctions Wednesday on 32 individuals and entities in Iran, the UAE, Turkey, China, Hong Kong, India, Germany and Ukraine that it said have helped procure key components, including missile propellant precursors, for the drone and missile programmes.

“Across the globe, Iran exploits financial systems to launder funds, procure components for its nuclear and conventional weapons programmes, and support its terrorist proxies,” Treasury’s under secretary for terrorism and financial intelligence, John Hurley, said in a statement.

Treasury targeted an international network known as the “MVM partnership”, which it said provides the ingredients for ballistic missile propellant from China and is run by UAE-based Marco Klinge, as well as Majid Dolatkhah and Vahid Qayum, who both operated out of Iran and Turkey.

The three men and entities connected to them are being blacklisted, according to the statement from Treasury. The US also targeted Ma Jie, an individual based in China, who it said helped Iranian defence officials meet with Chinese suppliers.
