President Donald Trump has expressed dissatisfaction with Oman regarding its discussions with Iran concerning the management of the Strait of Hormuz, according to officials. The strait is a narrow waterway located between Oman and Iran that serves as a critical route for global energy supplies.

The reported tension follows news of a deal between Oman and Iran. Oman has historically maintained a neutral diplomatic position in the Middle East, often acting as a mediator between Western nations and Tehran. However, U.S. officials stated that the current administration is unhappy with the specific terms or nature of the recent cooperation between the two regional neighbors.

Officials reported that the president threatened military action against Oman due to his disapproval of the agreement. The source did not provide specific details regarding the content of the Oman-Iran deal or the exact nature of the military threat. Separately, President Trump stated on Tuesday that the United States currently has no plans to conduct talks with Iran.

For Oman, a country with a Gross Domestic Product of approximately $108 billion, a shift in U.S. relations from strategic partnership to military threat marks a significant change in regional security. Oman has long served as a key site for U.S. military logistics and a diplomatic backchannel. If the U.S. were to carry out threats of kinetic action, it would set a precedent of targeting a traditionally neutral intermediary, potentially destabilizing shipping insurance markets and increasing the cost of goods transported by sea across the Middle East.

What happens next remains unclear as the administration has not released a formal timeline for action or further diplomatic demands. The source indicates that while the president expressed anger on Tuesday, the U.S. maintains no active negotiation track with Iran. Observers will be watching for official statements from the Omani Ministry of Foreign Affairs or the U.S. State Department regarding the status of their bilateral security agreements.
