The administration of Donald Trump has imposed fresh sanctions targeting a major Chinese refinery and a wide network of shipping entities linked to Iranian oil trade, significantly escalating its secondary sanctions strategy against Iran. The measures are aimed at curbing Tehran’s oil revenues, which Washington views as a critical source of funding.
Among the key targets is Hengli Petrochemical, a large refinery based in Dalian with a substantial processing capacity. US authorities allege that the facility has been receiving Iranian crude since 2023 and generating significant revenue streams tied to Iranian interests, including entities linked to its military apparatus.
In addition to the refinery, sanctions have been placed on around 40 shipping firms and oil tankers accused of facilitating the transport of Iranian crude across international markets. These actions form part of a broader effort to disrupt the logistical and financial networks that enable Iran to export oil despite existing restrictions.
The move reflects a stronger push toward “secondary sanctions,” which penalise not only Iran but also third-party countries, companies, and financial institutions that engage in business with it. Scott Bessent emphasised that the US intends to tighten pressure on intermediaries, buyers, and transport networks that sustain Iran’s energy exports. Financial institutions across regions such as Hong Kong, the United Arab Emirates, and Oman have also been warned about potential penalties for facilitating such transactions.
These sanctions come at a time of heightened volatility in global energy markets, particularly due to disruptions around the Strait of Hormuz, a critical route for oil shipments. The United States has also implemented a physical blockade in the region, further tightening constraints on Iranian exports and contributing to upward pressure on oil prices.
The timing is notable, as it precedes a planned meeting between Trump and Xi Jinping, adding a geopolitical dimension to the economic measures. The sanctions signal Washington’s willingness to extend enforcement beyond Iran itself and directly target international actors involved in its energy trade.
Overall, the action underscores a shift toward more aggressive enforcement, combining financial restrictions, maritime controls, and diplomatic pressure, even as global energy supply chains remain strained and sensitive to further disruptions.
