President Donald Trump’s administration is placing economic sanctions on a major China-based oil refinery and roughly 40 shipping companies and tankers involved in transporting Iranian oil.

The move, announced Friday and first reported by The Associated Press, makes good on Trump’s threat to impose secondary sanctions on companies and countries that do business with Iran. It›s also part of his Republican administration’s overall ramped-up campaign to cut off Iran’s key source of revenue — its oil exports.

Concurrently, the U.S. this month imposed a physical blockade on the Strait of Hormuz, the Persian Gulf waterway that is crucial to global energy supplies.

The sanctions, which cut off the companies from the U.S. financial system and penalize anyone who does business with them, come just a few weeks before President Donald Trump and China’s Xi Jinping are due to meet in China.

Included in Friday’s sanctions is Hengli Petrochemical’s facility in the port city of Dalian, which has a processing capacity of roughly 400,000 barrels of crude oil per day, making it one of the biggest independent refineries in China.

The Treasury Department says Hengli has received Iranian crude oil shipments since 2023 and has generated hundreds of millions of dollars in revenue for the Iranian military.

The advocacy group United Against Nuclear Iran said in February 2025 that Hengli is one of dozens of Chinese purchasers of Iranian oil.

China is the biggest buyer of Iranian oil, importing 80% to 90% of Iranian oil before the U.S.-Israeli war with Iran broke out, though the crude — transported by a shadow fleet of vessels — often has its origin obscured but arrives in China as oil from countries such as Malaysia. Smaller refineries, known as teapot refineries, typically are the buyers of Iranian oil. FATIMA HUSSEIN, WASHINGTON, MDT/AP
