On Friday, the United States stepped up its efforts against Iran by introducing maritime sanctions and targeting financial channels that convert oil sales into cash. Officials described this as a coordinated move to tighten the entire Iran–China energy trade.

The State Department announced sanctions on Qingdao Haiye Oil Terminal Co., Ltd., a company based in China. They are accused of importing “tens of millions of barrels” of Iranian crude starting from early 2025 and helping to send billions of dollars to Tehran using deceptive shipping practices like ship-to-ship transfers.

Officials pointed out that this terminal accepted cargo from sanctioned ships that were involved in secretive transfers. This highlights long-standing U.S. concerns about STS hubs near Singapore and the broader “dark fleet” system that transports Iranian oil.

In addition to targeting the terminal, the U.S. also sanctioned an individual connected to it, as well as a tanker and vessel management companies already linked to Iran’s oil export network.

While the State Department focused on the physical transport of oil, the U.S. Department of the Treasury targeted the financial side, sanctioning three Iranian currency exchange houses and their networks that are said to process billions of dollars each year. These entities are vital for converting oil revenue into usable funds for the Iranian government and its regional allies.

These actions demonstrate a more comprehensive U.S. strategy that goes beyond just tracking tankers and terminals; it aims to address the entire lifecycle of Iranian oil.

The sanctions were applied under Executive Order 13846 for maritime issues and Executive Order 13902 for financial designations, both related to the Trump administration’s “maximum pressure” policy.

“These measures disrupt Iran’s ability to fund terrorism and its proxies, develop weapons, and pose threats to the region,” said State Department spokesperson Thomas “Tommy” Pigott in a statement.

In simple terms, these coordinated actions increase compliance risks for many players involved. Any part of the process—whether that's handling cargo, chartering, financing, or transactions—could now be subject to U.S. sanctions.

This move is part of Washington's broader Economic Fury campaign, with increasing attention on infrastructure in China seen as a key outlet for Iranian crude, while enforcement efforts strive to keep up with changing evasion tactics in global shipping routes.
