The latest

The White House believes talks between Iran and Oman broke down weeks ago, closing a channel that had appeared to offer one of the few fruitful negotiating paths amid tensions with Tehran. President Donald Trump is now emphasizing economic pressure while taking his latest step away from military escalation in Iran. He threatened “economic warfare” and said Washington would penalize countries continuing to do business with Tehran.

Details

• US assessment: A US official and a White House official said the administration concluded that the Iran-Oman discussions had broken down weeks earlier. Their account places the collapse before recent signs that the diplomatic channel had stalled, despite previously appearing capable of producing progress.
• Rare pathway: The discussions between Tehran and Muscat had emerged as an unusual area of potentially productive diplomacy. Their breakdown removes a negotiating route that had stood out while Washington and Tehran remained at odds over the broader direction of their relationship.
• Hormuz proposal: The talks had frustrated Trump by raising the prospect of a possible tolling arrangement in the Strait of Hormuz. That proposal became a source of concern for the president within a process that otherwise appeared to offer a path toward negotiations.
• Omani response: The Omani embassy did not respond to a request for comment on Washington’s assessment of the negotiations. The request addressed the US view that discussions involving Oman and Iran had already broken down weeks before the latest signs of a stall.
• Economic warning: Trump issued his threat in a Truth Social post, saying the United States would impose penalties on any country doing business with Iran. By describing the measures as “economic warfare,” he directed the warning at Tehran and its international commercial partners.
• Diplomatic pause: The president has cut off future negotiations with Iran for the foreseeable future. At the same time, he remains optimistic that sustained economic pressure can eventually compel Tehran to return, leaving coercive measures as Washington’s immediate instrument for pursuing that outcome.
• Current framing: Trump described the situation with Iran as “so good” despite the administration’s assessment that the Oman channel had collapsed. His position combines confidence in current conditions with a retreat from immediate military escalation and the suspension of near-term diplomacy.

Between the lines

Trump is keeping renewed negotiations as his intended destination while ruling them out for now. His approach relies on penalties against Iran and countries trading with it to create the pressure he believes could eventually revive diplomacy.

What’s next

The next concrete indicator will be any US announcement of penalties against a country doing business with Tehran following Trump’s threat. A decision to reopen negotiations would signal whether that economic-pressure strategy has moved Iran back toward talks.
