Treasury Secretary Scott Bessent said on Monday that new US sanctions aim to block all potential sources of revenue for Iran and told nations to cut economic ties to Tehran or face retaliation.Bessent said it’s “no longer acceptable to operate in the gray spaces” of the conflict.He did not name what countries could face potential secondary sanctions from the United States, but China, Turkey and the United Arab Emirates are Iran’s largest trade partners.”Let there be no ambiguity as to the position of the United States,” Bessent told a news conference.”An economic engagement of any kind with this murderous regime will expose those responsible to the full reach of American power.”
