US Sanctions Chinese Refiner Over Iran Oil Trade

The Trump administration has imposed sweeping economic sanctions on Hengli Petrochemical, one of China's largest independent oil refineries, along with approximately 40 shipping companies and tankers involved in transporting Iranian oil. The Treasury Department announced the measures Friday, making good on the administration's threat to apply secondary sanctions on entities that do business with Iran. The sanctions target Hengli's facility in Dalian, which processes roughly 400,000 barrels of crude oil per day and has received Iranian shipments since 2023, generating hundreds of millions of dollars in revenue for the Iranian military, according to the department. Treasury Secretary Scott Bessent stated the administration will continue to constrict the network of vessels, intermediaries, and buyers Iran relies on to move its oil to global markets. Earlier this month, the department sent letters to financial institutions in China, Hong Kong, the United Arab Emirates, and Oman threatening secondary sanctions for doing business with Iran. The measures come as the United States also imposed a physical blockade on the Strait of Hormuz, the Persian Gulf waterway critical to global energy supplies, and follow escalating tensions as talks may resume between U.S. and Iranian officials in Pakistan regarding Pentagon operations in the Middle East. The sanctions announcement arrives just weeks before President Donald Trump and China's Xi Jinping are scheduled to meet in China, potentially complicating bilateral relations. Global energy markets are already experiencing significant turbulence as conflict around the Persian Gulf disrupts oil and natural gas shipments, driving prices higher. The Treasury Department has attempted to mitigate the impact of rising oil prices by issuing temporary sanctions waivers on Russian oil and a one-time waiver for Iranian oil already at sea.
