US Sanctions on Iran Hit Chinese Supply Chain Firms

The US Treasury Department sanctioned dozens of China and Hong Kong-based firms and individuals for allegedly helping Iran procure sensitive technology and move money, while stopping short of targeting major Chinese banks. The sanctions, part of Treasury Secretary Scott Bessent's Operation Economic Outcast, target a procurement network built around Hong Kong-based Sweet Ocean Industrial Ltd. The company allegedly acquired laser optics equipment for Iran's Malek Ashtar University of Technology, which has ties to Iran's defense sector. Three China-based individuals were also named. Washington's restraint on major Chinese banks appears deliberate, as such a move could trigger significant economic and diplomatic blowback. The action mirrors the US approach to Russia sanctions, targeting intermediaries and shipping firms in Hong Kong. However, the impact remains uncertain since many targeted firms are private companies with limited ties to the US financial system.
