China warned it will take all necessary steps to protect its interests after the United States announced fresh sanctions aimed at Iran’s trade partners.

China announced on Tuesday that it will "take all necessary measures to firmly safeguard its own rights and interests" after the United States unveiled a new round of sanctions aimed at companies dealing with Iran. The statement came from foreign ministry spokesman Lin Jian, who said the measures were "illegal unilateral sanctions" that threaten Chinese businesses.
The United States said the sanctions target entities that facilitate Iran’s oil exports and financial transactions, part of a broader effort to pressure Tehran over its regional activities. For Beijing, Iran is its largest oil customer, accounting for roughly ninety percent of Tehran’s oil exports. Any disruption to that flow could ripple through global energy markets, raise oil prices and affect Chinese firms that rely on Iranian crude.
Washington’s sanctions also include secondary penalties that could bar non‑US firms from using the US financial system if they continue to trade with Iran. United States officials warned that any ship or boat placing new mines in the Strait of Hormuz would be destroyed, signalling a willingness to use force to enforce the measures.

Analysts expect Beijing to explore alternative payment mechanisms and to increase diplomatic outreach to Tehran. The move may also prompt China to lobby other major economies to oppose the sanctions, echoing past calls for a multilateral approach to Iran’s oil trade.
In the short term, oil traders are likely to price in higher risk premiums for shipments that pass through the Strait of Hormuz. Longer term, the standoff could push both powers to seek a negotiated settlement, especially as European economies grapple with the side effects of the conflict, as seen in the recent revision of German growth figures despite the turmoil.
Watch for further statements from both capitals and any retaliatory steps from Iran, which has vowed to hit back. The evolving diplomatic dance will shape not only regional stability but also the flow of energy to markets worldwide.
