United States Treasury Secretary Scott Bessent has declared an economic onslaught on Iran's financial connections around the world. However, China's position as Iran's largest trading partner and leading oil buyer may limit the campaign's effectiveness.

The U.S. is attempting to isolate Iran from its remaining economic partners. At the same time, President Donald Trump is preparing to host Chinese leader Xi Jinping next month to maintain a fragile trade truce. Bessent's remarks did not include specifics on how the administration would target China, raising doubts about the campaign's potential impact.

The U.S. must balance applying maximum pressure on Iran with avoiding higher tensions with China that could be costly to the American economy.
