U.S. Sanctions Target Chinese Refinery and Iran’s Shadow Fleet Ahead of Diplomatic Talks

Sanctions
On 24 April 2026 the U.S. Treasury’s Office of Foreign Assets Control sanctioned Hengli Petrochemical (Dalian) Refinery and roughly 40 shipping firms and tankers identified as part of Iran’s “shadow fleet,” citing the “Economic Fury” campaign to cut Iran’s oil revenue.
Background & Key Players
Iran relies on oil exports and evades sanctions with a “shadow fleet” and sales to Chinese “teapot” refineries, which before the February 2025 war supplied 80-90 % of its crude. Treasury Secretary Scott Bessent announced sanctions on Hengli Petrochemical (Dalian) Refinery, a buyer linked to the Revolutionary Guards Corp.
Impact & Data
Hengli processes about 400,000 bpd, one of China’s largest independent refineries. The Treasury lists roughly 40 shipping firms, though Bloomberg cites 19 vessels. The shadow fleet moves millions of barrels via ship-to-ship transfers, and cutting these flows aims to weaken Tehran’s ability to fund its military, proxies and nuclear program.
Official Responses
Bessent said the measures will further restrict the network of vessels, intermediaries and buyers that move Iranian oil, and warned that anyone facilitating such flows could face U.S. sanctions. The Treasury called Hengli a key customer of Tehran and described the campaign as a financial stranglehold on Iran.
Opposition
China’s embassy warned the sanctions “disrupt normal economic and trade exchanges” and infringe on Chinese companies’ rights, arguing they violate trade norms and could heighten U.S.–China tensions before the May summit.
Conflicts
The Treasury cites “around 40” shipping firms, while Bloomberg lists 19 specific vessels. Descriptions of Hengli range from a “smaller” teapot refinery to one of China’s largest independent refineries. No Iranian comment appears in the sources.
