China has rejected a U.S. effort to enlist Beijing in a broader economic campaign against Iran as Washington prepares tougher sanctions targeting Tehran and countries that continue doing business with it. The dispute adds another layer to tensions between the United States and China as the Iran conflict continues to disrupt regional energy markets and international trade.
Oil shipments through the Strait of Hormuz have been heavily disrupted as the United States and Iran remain locked in a prolonged conflict.
The Trump administration has intensified its economic pressure on Iran nearly six months into the conflict, with Treasury Secretary Scott Bessent calling on China and other countries to support measures designed to restrict Tehran's access to international trade and oil revenue. The United States has warned that countries and companies continuing significant commercial ties with Iran could face penalties, while China has said it opposes unilateral sanctions that are not authorized by the U.N. Security Council or consistent with international law. China is particularly important to Iran's economy because it remains the main destination for Iranian oil exports.
Beijing's position reflects its longstanding opposition to broad U.S.-led sanctions against Iran and its economic relationship with Tehran. China has continued purchasing Iranian oil despite years of American sanctions, while Washington has increasingly used secondary sanctions to pressure third-country companies and financial institutions involved in Iranian trade. The United States has previously targeted Chinese entities over their dealings with Iranian oil, underscoring the potential for the latest dispute to further complicate already strained U.S.-China relations.
The disagreement comes as Washington seeks to increase economic pressure after military operations and diplomatic efforts have failed to produce a lasting settlement. The Strait of Hormuz remains a central concern because disruptions to the waterway have sharply affected oil shipments and contributed to wider economic uncertainty. With China rejecting the U.S. call for additional sanctions, Washington faces a more difficult effort to limit Iran's remaining international trade networks while Beijing's continued economic engagement with Tehran provides Iran with an important commercial outlet.
