U.S. Sanctions Chinese Refinery And 19 Tankers In Iran Oil Crackdown

The U.S. Treasury on April 25, 2026, announced sanctions on a Chinese refinery and 19 tankers accused of transporting Iranian crude, aiming to cut Tehran's oil revenues and disrupt its "shadow fleet."

Officials named Hengli Petrochemical among the targets and blacklisted 19 tankers and associated shipping firms. The action also froze cryptocurrency wallets and other assets the Treasury said funded Iran's military operations.

The move follows an intensified U.S. campaign to squeeze Iran's oil income after months of regional conflict and economic pressure that escalated into open war. The sanctions were announced as U.S. and Iranian delegations prepared to meet in Pakistan, a pairing that frames pressure and diplomacy as simultaneous levers.

The announcement came alongside a 90-day extension of a Jones Act waiver and a near blockade of the Strait of Hormuz, where daily transits plunged from roughly 140 to as few as seven ships. Market watchers and social media noted some Chinese refiners are still importing Iranian oil, making enforcement of the blacklist the next key test.
