Summary · why it matters
The US government announced a new round of sanctions against a total of 13 individuals and entities with networks spanning several countries, including Russia, China, Hong Kong, Pakistan and Iran, accusing them of helping Iran procure weapons and components related to its military programmes. The US Treasury and State Departments announced the measures on 29 September, part of the administration of President Donald Trump's effort to increase economic pressure on Iran and push it into negotiations to end the war that began after the United States and Israel attacked Iran on 28 February 2026. US Treasury Secretary Scott Bessent said the United States would not tolerate any support that aids the Iranian government and would continue to identify, expose and cut off networks that assist Iran from the economic system. Those sanctioned include Seyyed Asghar Alizadeh Tabatabaei, a representative of the Iranian Armed Forces defence and logistics agency in Beijing, Kavoshcom Asia R and D Group, an Iranian company, EC Mojo Technology Co Limited, based in Hong Kong, and Li Fen, a representative of a Chinese company, as well as Waseem Pasha Tajammal, chairman of Cavalier Group, a private defence company in Pakistan, Joint Stock Company Experimental Design Bureau Named After A.S. Yakovlev, a Russian aircraft manufacturer, MG-Flot LLC, a Russian shipping company, and Saha Airlines, an Iranian airline. Meanwhile, Brett Erickson, managing director of Obsidian Risk Advisors, assessed that the latest sanctions round may have limited effect on Iran's ability to fire missiles and drones around the Strait of Hormuz, seeing the measures as carrying more weight as a political signal than as a significant reduction of Iran's military capabilities.
