The Trump administration expands its Iran sanctions, placing nearly 60 individuals and entities in China and Hong Kong under new Treasury designations announced by Secretary Scott Bessent. The measures are carried out under a campaign referred to as “Operation Economic Outcast,” aimed at cutting off Iran’s trade, technology, and financial channels.

Treasury focuses on alleged procurement and logistics networks that support Iranian defense-linked activity, including Hong Kong-based Sweet Ocean Industrial Ltd., which the US accuses of helping obtain laser-optics equipment for Malek Ashtar University of Technology. Several related firms in Hong Kong and Shenzhen are also named, alongside Chinese individuals including Li Na, Tian Jianbai, and Zhang Limei, who are accused of coordinating procurement tied to Iran’s nuclear and missile research.

Multiple outlets report that the US stops short of targeting major Chinese banks. That approach is presented as a way to increase pressure on Tehran while limiting the risk of broader financial and diplomatic spillovers. China signals it will not retreat from its Iran-related economic ties and warns that unilateral US sanctions could intensify the conflict, with some reporting on the possibility of retaliation if the measures broaden to include major Chinese firms.
