U.S. Sanctions Target Chinese Oil Refinery Tied to Iran
The U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) imposed sanctions on a significant Chinese oil refinery and numerous ships associated with Iran’s so-called “shadow fleet,” intensifying efforts to impede Iran’s primary revenue stream.
In a recent press release, officials pointed out that these sanctions impact Hengri Petrochemical, one of the largest oil buyers from Iran. The sanctions also extend to a network of shipping companies and tankers that transport vast amounts of oil products to international markets.
According to the Treasury Department, these vessels form a crucial support line for what they describe as Iran’s “unstable regime.”
Crackdown on Iranian Oil Sales
This initiative is part of a broader strategy called Economic Fury, which aims to constrain Iran’s economy by limiting its capacity to export oil. The U.S. argues that the revenue generated is fueling the regime’s military ambitions and destabilizing activities throughout the Middle East.
Treasury Secretary Scott Bessent remarked that “Economic anger is putting a financial strain on the Iranian regime, preventing it from invading the Middle East and helping to rein in its nuclear ambitions.”
The Hengli Petrochemical (Dalian) Refinery, referred to as a “teapot” refinery, is known for buying crude oil from countries under sanctions and others at lower prices. This facility has reportedly been receiving Iranian oil shipments from sanctioned vessels since at least 2023, contributing millions in revenue to Iranian military operations.
Furthermore, Hengri also engages with Sepal Energy Jahan Nama Pars, identified by U.S. authorities as a front for the Iranian military, facilitating oil sales abroad. This company utilizes a web of intermediaries and ships to transport sanctioned oil on behalf of Iran’s military, which helps finance their programs and regional proxy activities.
Networks of Oil Sales Targeted
The recent sanctions are not only focused on the refinery but also target the entities that facilitate these oil exports. This “shadow fleet” includes older tankers and front companies that maneuver around sanctions, obscuring the source of their shipments.
To avoid detection, these vessels frequently transfer cargo between ships in international waters. The Treasury reported that 19 ships were specifically named in the latest operation.
As part of the ongoing campaign by the Trump administration to exert maximum pressure on Iran, U.S. officials maintain that oil exports are vital to Iran’s economy. The goal is clear: to restrict the government’s ability to fund military operations and support proxy groups, while also stalling its nuclear ambitions.
Treasury officials have signaled that additional sanctions may follow as the U.S. ramps up its efforts to dismantle the networks that enable Iran to sell oil globally.
