Trump Hits Chinese Refinery Over Iranian Oil Ahead of China Visit

President Donald Trump’s newest punitive action focuses on the Hengli Petrochemical refinery in Dalian, China—an oil plant that has been importing Iranian crude since 2023. The move follows Trump’s earlier pledge to impose secondary sanctions on any company or nation that continues trading with Iran, a strategy aimed at straining the Iranian economy.

Key Point: Hengli has reportedly generated hundreds of millions in revenue for the Iranian military through its oil purchases.

The sanction comes just weeks before Trump is slated to meet Chinese President Xi Jinping in Beijing, heightening diplomatic friction amid an ongoing trade dispute.

Why China Matters

• China is a primary buyer of Iranian oil, accounting for 80–90 % of shipments before the recent U.S.–Israeli conflict.
• Many imports are camouflaged, listed under names of other countries (e.g., Malaysia) and processed by small “teapot” refineries.
• The U.S. Treasury claims Hengli’s dealings have directly benefited Iranian state actors.

Treasury’s Hardening Stance

Treasury Secretary Scott Bessent warned that the U.S. will intensify restrictions on:

• Vessels transporting Iranian oil
• Middlemen and buyers worldwide

Earlier this month, Bessent threatened secondary sanctions against banks in China, Hong Kong, UAE, and Oman that facilitate Iranian trade.

Global Energy Context

• The Persian Gulf conflict has disrupted oil and gas flows, driving prices higher.
• To mitigate the price surge, the Treasury offered temporary waivers on Russian oil and a one‑time waiver for Iranian oil already at sea.

China’s Response

• Beijing protested the sanctions, citing disruptions to international trade and harm to legitimate Chinese businesses.
• Despite protests, many Chinese firms continue to comply with U.S. rules due to their reliance on the American financial system.

Implications for Iran and U.S.–China Relations

• Iran demands that sanctions be lifted as a precondition for any peace talks.
• The impact of this new sanction on Iran’s strategy and U.S.–China relations, especially ahead of the upcoming summit, remains uncertain.
