The Treasury Department on Monday sanctioned three individuals and nine companies it accused of helping Iran’s Islamic Revolutionary Guard Corps sell and ship crude oil to buyers in China, naming front companies in Hong Kong, the United Arab Emirates and Oman in the designation. The Office of Foreign Assets Control posted the action under its Iran-related and counter-terrorism authorities; Treasury Secretary Scott Bessent said in the announcement that the move was part of a continuing campaign to choke off the regime’s funding for weapons programs, proxies and nuclear ambitions. The package landed days before President Donald Trump’s scheduled meeting with President Xi Jinping, and Treasury framed it as pressure on the Chinese end of the supply chain as much as on the Iranian end.
What was designated, and on what authority
OFAC listed 12 targets under Executive Order 13224 (counter-terrorism) and the Iran-related sanctions authorities, according to the agency’s recent-actions register dated May 11. The designated companies include Hong Kong Blue Ocean Ltd and Hong Kong Sanmu Ltd, which Treasury described as cover companies that arrange the sale and shipment of Iranian oil; Dubai-based Ocean Allianz Shipping LLC and Sharjah-based Atic Energy FZE, which Treasury said facilitated shipments on five sanctioned shadow-fleet tankers during 2025; Oman-based Zeus Logistics Group, named for arranging vessels to carry Iranian cargoes; and two Hong Kong-based purchasers, Jiandi HK Ltd and Max Honor International Trade Co Ltd, identified as IRGC counterparties that bought tens of millions of dollars’ worth of Iranian crude. The Bureau referred to the broader designation set as part of the administration’s “Economic Fury” enforcement campaign.
The named Treasury position
Treasury will continue to cut the Iranian regime off from the financial networks it uses to carry out terrorist acts and to destabilize the global economy. — Scott Bessent, U.S. Treasury Secretary
Bessent’s statement, issued through the Treasury press office, ties the May 11 action to the administration’s posture toward Tehran since the February 28 outbreak of fighting and the April 8 Pakistan-brokered ceasefire. Treasury’s theory of the case, restated on Monday, is that the IRGC routes crude through layered shell companies in permissive jurisdictions, sells through cover firms, and is paid through intermediaries that never appear on the bill of lading. The May 11 list names entities at each link in that chain: arrangers, ship managers, and purchasers. The agency did not disclose dollar values for individual transactions.
Timing: ahead of the Trump–Xi meeting
The designations come days before Trump is expected to press Xi on Chinese imports of sanctioned Iranian crude and on Beijing’s influence over Tehran during the broader Strait of Hormuz standoff. China is the destination for the overwhelming share of Iranian oil that moves outside the formal market; the independent “teapot” refineries on China’s east coast have absorbed most of the discounted barrels for the past two years. Treasury issued a separate OFAC alert on April 30 warning U.S. and third-country counterparties of the sanctions risk of dealing with those refineries. The Monday action lands inside that ongoing pressure track, not as a one-off.
What the package does, and does not, change
Designation under EO 13224 freezes any U.S. assets of the listed entities and bars U.S. persons from transacting with them; under the Iran-related authorities, it also exposes foreign banks and counterparties to secondary sanctions if they knowingly facilitate significant transactions for the designated firms. What it does not do is interdict cargo at sea or stop tankers from loading at Iranian terminals. The visible consequence will be on banking and ship-management relationships at the named firms, and on the willingness of port agents and insurers in third countries to handle business that touches them. Brent crude was little changed on the day, trading inside its post-ceasefire range as traders treated the action as an extension of the existing enforcement track rather than a new front.
The China question, narrowly framed
Treasury’s targeting of two Hong Kong-based purchasers — Jiandi HK Ltd and Max Honor International Trade Co Ltd — is the operative move. Treasury has reached up the chain past the shippers to the buyers, and it has done so days before the Trump–Xi meeting. That sequencing is the point Treasury is making in public, and the point American officials are likely to make in private: the United States can name the Chinese-side entities that move Iranian crude, and it can keep doing so. Whether Beijing chooses to insulate, replace or pull back from those entities is the response Treasury is asking for.
