U.S. Pushes New Sanctions to Further Isolate Iran's Trade

Iran’s economy, already strained by high inflation, long-standing Western sanctions and reduced oil revenue, faces additional pressure after the United Arab Emirates suspended trade relations last week. The move is part of a U.S. effort, described by Treasury Secretary Scott Bessent as “Operation Economic Outcast,” to compel other nations to cut financial dealings with Tehran. > “Those who stand with the United States will reap the rewards of our partnership,” Bessent said, adding that countries maintaining ties with Iran should expect isolation.

In 2024 Iran’s global trade was valued at about $125 billion, with the UAE, China and Turkey accounting for roughly three-quarters of its imports. The UAE had served as a key conduit for goods and payments, re-exporting items that foreign suppliers preferred not to ship directly to Iran. “From Iran’s perspective, the UAE can be replaced, but the Iranians are openly saying it’s not going to happen overnight,” said Alex Vatanka, senior fellow at the Middle East Institute.

China, Iran’s largest export market and a major buyer of its crude, is less dependent on the relationship and may resist U.S. pressure. David Lubin of Chatham House warned that aggressive action against Chinese banks could heighten trade tensions ahead of a planned meeting between President Donald Trump and Chinese leader Xi Jinping. Former U.S. ambassador Daniel Fried noted that the Obama administration had already pushed Beijing to reduce Iranian energy imports.

Regional partners such as Turkey, Pakistan and Iraq balance economic ties with Iran against the risk of secondary sanctions. Turkey recently settled a U.S. dispute over a bank that helped Iran evade sanctions, and analysts say it is unlikely to become a new conduit for prohibited trade. Iraq relies on Iranian imports but has been moving closer to Washington, while Oman’s mediation role between Tehran and Washington has become precarious after a Trump warning.

Alternative routes, such as Pakistan’s Gwadar port or a proposed Caspian Sea “road of life,” are being explored, but logistical and political challenges limit their immediate impact. Russia has begun routing some exports to Iran via Caspian ports, yet neighboring Caspian states are not expected to expand trade quickly.

Overall, the success of the United States’ intensified sanctions campaign will depend on whether China, Russia and regional economies can sustain Iran’s trade needs without succumbing to U.S. pressure.
