China rejects US sanctions on its refineries buying Iranian oil as UN Security Council presidency begins

China's Commerce Ministry announced on May 2 that it "will not comply" with recent US sanctions targeting five Chinese refining firms for purchasing Iranian oil, escalating a confrontation weeks before the planned Trump-Xi summit in Beijing on May 14–15. The US Treasury on April 24 sanctioned Hengli Petrochemical (Dalian) and approximately 40 shadow-fleet vessels, and on April 28 warned banks about dealings with independent Chinese "teapot" refineries that purchase roughly 90% of Iran's oil exports. Separately, China's UN Ambassador Fu Cong on May 1 called maintaining the Iran war ceasefire an "urgent necessity," as China began its month-long presidency of the UN Security Council. Fu rejected US allegations of military cooperation between China and Iran as "false" and said if the Strait of Hormuz remains closed during Trump's visit, it will be high on the bilateral agenda.
Strategic interpretation
China is using its UN Security Council presidency to position itself as a diplomatic broker on the Iran war while simultaneously rejecting US pressure on oil purchases — a calibrated defiance. The timing, weeks before the Trump-Xi summit, signals Beijing's willingness to separate trade negotiations from Iran policy. Trump faces a choice: de-escalate on oil sanctions to secure a trade deal, or escalate enforcement and risk the summit failing before it begins. The "teapot" refinery structure — small, opaque, and hard to monitor — has historically frustrated US enforcement efforts, suggesting China may be betting that the sanctions cannot be effectively policed.
