China decries U.S. sanctions on Iran as illegal and unilateral
China’s foreign ministry spokesman Lin Jian publicly rebuked the United States for announcing a broadened set of economic sanctions aimed at weakening Iran and its business allies, including Chinese state‑owned companies. Lin called the policies “illegal unilateral sanctions” and stated that Beijing would adopt “all necessary measures” to protect its interests.
The backlash followed Treasury Secretary Scott Bessent’s remarks that any country or institution engaging financially with Iran would be isolated, and that the U.S. would treat banks and firms that continue dealings with the Iranian regime as collaborators in the blockade. Bessent described the package as the “single greatest financial offensive ever” against Tehran and noted that the new sanctions would effectively tighten the noose around Iran’s revenue sources.
China’s role as Iran’s principal oil buyer—although its volume has declined under U.S. pressure—was highlighted as a key concern. Lin said bilateral cooperation had always been pursued within the framework of international law and should remain uninterrupted.
Bessent, speaking without naming specific nations, warned that even foreign banks could be brought under U.S. jurisdiction. When queried about Chinese financial institutions, he reiterated that “no one is above the reach of U.S. sanctions.”
Implications for the global rare‑earth supply chain
China’s importance as the world’s leading processor of rare earths and other critical minerals adds to the stakes. Beijing has already tightened export controls on rare earths amid a prior trade spat with the U.S., and U.S. officials fear that retaliation could ripple through global high‑tech manufacturing.
The U.S. move is set against the backdrop of a broader effort to pressure Iran into negotiation, with U.S. officials labeling the package as an “economic D‑Day.” It arrives roughly six months after the onset of escalating tensions that have already pushed oil prices higher.
Iran and other partners weigh in
Iran’s economy minister Ali Madanizadeh announced Tehran’s readiness for the expanded sanctions and pledged a two‑year plan to manage the fallout. He characterized the U.S. pressure as another blow to the American narrative. Iran’s neighboring nations—Pakistan, Turkey and Iraq—expressed a practical concern: they cannot afford to cut links with Tehran.
Analysts noted that the sanctions may have limited immediate impact on Iran’s oil flows, largely because 90% of Iranian crude is exported to China, which has historically ignored U.S. directives. While U.S. officials claim the measures will severely cut Iranian revenues, the real effect could be muted depending on China’s compliance.
Other key partners—India and Russia—have yet to make a public response, but they face their own calculations regarding economic ties and U.S. pressure.
Looking ahead
The confrontation arrives just before scheduled talks between President Trump and President Xi Jinping. Both sides appear to anticipate a complex discussion that may touch on sanctions, trade, and regional security. U.S. officials warn that Beijing could counteract with its own set of measures aimed at critical sectors; meanwhile, China’s stance on multilateral versus unilateral sanctions is unlikely to change.
As U.S. policy is rolled out, market watchers will monitor not only oil and energy prices but also the stability of the rare‑earth supply chain and the global financial system’s exposure to cross‑border sanctions.
