Treasury Secretary says U.S. will impose sanctions on Iran, urges China to cooperate

What This is

• Treasury Secretary Scott Bessent says the U.S. will announce a new set of sanctions meant to economically isolate Iran.
• The administration says the measures will be unusually severe, with Bessent calling them the “toughest sanctions in history” and aimed at crippling Iran’s government finances.
• Trump has warned that countries, banks, and companies that keep trading with Iran could face U.S. penalties, including so-called secondary sanctions that punish non-U.S. actors.
• U.S. officials are pressing allies and China in particular to cooperate, since China is described as the largest buyer of Iranian oil and a key part of Iran’s trade network.
• Iran has rejected the U.S. threats, calling them “economic terrorism” or a diversion, as negotiations remain stalled and the Strait of Hormuz remains a flashpoint.
• Iran and Oman are reported to be close to a separate arrangement to manage Hormuz shipping routes, but the U.S. has signaled it will not accept terms that fail to restore free passage.

Why This Matters

• If Washington starts penalizing non-U.S. banks and firms, the dispute can spread from Iran to China, the Gulf, and other major trading hubs.
• Economic “maximum pressure” raises a moral question: whether hurting a whole economy is a justified way to change a government’s behavior.
• The campaign could shift the Iran conflict from bombs to wallets, but it can also invite retaliation at sea or through proxy groups.
• Moves to route trade outside the dollar and U.S.-linked payment systems could weaken the long-term reach of American sanctions.
