China Chides U.S. Over New Iran Sanctions, Threatens Countermeasures

The United States unveiled a new package of economic sanctions that extend beyond Iran to include its trading partners, drawing a sharp rebuke from China. According to Foreign Ministry spokesman Lin Jian, the U.S. moves are "illegal unilateral sanctions" and China will take "all necessary measures" to protect its interests, especially as Beijing remains Iran’s biggest oil buyer.

U.S. Treasury Secretary Scott Bessent described the expansion as "the single greatest financial offensive ever" against Iran, warning that any country aiding Tehran would face isolation. Though the sanctions fall under U.S. jurisdiction, Bessent underscored that no entity is exempt from compliance, including major Chinese banks, if they facilitate Iranian trade.

China’s swift response ahead of planned talks between President Donald Trump and President Xi Jinping underscores the strategic stakes. Beijing has already tightened export controls on rare earths—critical for high‑tech manufacturing—as part of earlier trade negotiations with Washington.

Iranian officials, meanwhile, claim the regime is ready for the expanded sanctions, warning the U.S. of a "two‑year plan" to absorb the economic blow. Analysts observe that each sanctions set offers limited immediate leverage, given that roughly 90% of Iran’s oil goes to China, a country historically uncooperative with unilateral U.S. measures.

Other nations linked to Iran—such as India, Russia, Turkey, Pakistan and Iraq—remain cautious, weighing the benefits of continued engagement against the risk of U.S. penalties. For now, it appears the new U.S. sanctions will have a muted short‑term effect on Iran’s energy revenues, but they mark a significant escalation in the ongoing economic warfare.
