U.S. President Donald Trump announced that all transactions involving Iranian oil or petrochemical products must cease, warning that any individual or nation engaging in such purchases would face immediate secondary sanctions. He stated on Truth Social on Thursday, “They will not be permitted to conduct any business with the United States of America in any capacity.”
Trump’s remarks come after the latest round of U.S. negotiations with Iran regarding its nuclear program was postponed, with a senior Iranian official indicating that a new date would be determined based on the U.S. state.
Trump administration has imposed a series of sanctions targeting Tehran, including actions against a crude oil storage facility in China and an independent refiner accused of participating in illegal oil and petrochemical trade.
In February, Trump reinstated a “maximum pressure” strategy aimed at reducing Iran’s oil exports to zero and hindering its nuclear weapon development. Secondary sanctions are measures taken by one country to penalize another for trading with a third country by restricting access to its own market, a particularly effective strategy for the U.S. due to its economic size.
Analysts suggest that to effectively limit Iran’s oil exports, the U.S. would need to impose secondary sanctions on entities like Chinese banks that facilitate Iranian oil purchases, as China is the largest importer of Iranian crude.
