JD Vance cancels Switzerland trip as US-Iran ceasefire talks stall
The White House has said US Vice President JD Vance will no longer travel to Switzerland for planned talks on the next steps in the US-Iran agreement. The meeting had been expected to focus on how to implement the 14-point accord that ended the war between the two countries. A White House spokesperson said the logistics of the negotiations had "never been simple or predictable" and that Vance was not departing as planned.

The cancellation adds to uncertainty around a proposed formal signing ceremony in Geneva, which US officials had discussed for the agreement. Iran's foreign ministry has already cast doubt on the need for such a ceremony, saying both presidents signed the agreement on Wednesday. Before Vance's announcement, the semi-official Tasnim news agency said Iranian negotiators wanted to see signs that the interim deal was being carried out before the next round of peace talks could begin.
The talks are part of a fragile effort to move from a ceasefire to technical implementation after the two sides extended the truce by at least 60 days under the accord. The agreement is also tied to wider questions about sanctions relief, asset unfreezing and oil exports, all of which make the follow-up phase politically sensitive in Washington and Tehran. The diplomatic process is taking place against a backdrop of a war that has killed at least 7,000 people, pushed up energy prices and shaken global markets.
The dispute over the Geneva meeting also highlights how much remains unresolved even after the fighting was declared over. Israel was not included in the peace talks and has distanced itself from the US-Iran accord, while continuing its fighting against the Iranian-allied Hezbollah militant group in Lebanon. That has raised questions about whether the ceasefire arrangement can hold beyond the immediate US-Iran track.

In Washington, the deal is also drawing scrutiny from Republican lawmakers, some of whom have questioned whether President Donald Trump gave up too much to end the conflict. Trump had previously said he would only end the war with Iran's "unconditional surrender," but the memorandum signed with Iran instead includes sanctions relief, the unfreezing of tens of billions of dollars in assets and immediate US waivers for Iran to export oil. Iran's Supreme Leader Ayatollah Mojtaba Khamenei has said Trump signed the deal "out of desperation," underscoring the political tension surrounding the agreement.
What remains unclear is when the Switzerland talks will be rescheduled and whether Iranian negotiators will travel to Geneva at all. It is also not yet clear how the technical discussions will be structured or whether a separate letter involving the International Atomic Energy Agency will become part of the implementation process. The next stage will depend on whether the United States, Iran and other relevant actors can agree on verification and compliance terms that support the wider ceasefire.
The White House said on Thursday that US Vice President JD Vance will no longer travel to Switzerland for planned talks on the next steps in the US-Iran agreement. The meeting had been scheduled for Friday and was expected to focus on implementation details after the deal that ended the war in the Middle East. A White House spokesperson said the logistics of the negotiations had "never been simple or predictable" and that Vance was not departing that night.
The postponement comes as Trump envoy Steve Witkoff briefed members of Congress on possible arrangements for international monitoring of Iran's nuclear programme. According to people familiar with the closed-door discussion, Witkoff said Iran would invite the International Atomic Energy Agency to inspect its nuclear sites and begin work on identifying the locations of Tehran's enriched material, which is believed to be buried under rubble. He also said a side letter had been drafted between Tehran and the agency, extending the invitation to Director-General Rafael Mariano Grossi.

Witkoff told lawmakers that the agreement struck by the United States and Iran did not include any side deals. He said the separate letter would allow Grossi to bring US nuclear inspectors to Tehran, according to the account given by people familiar with the briefing. The comments suggest that inspection access and verification remain central to the fragile follow-up phase of the agreement.
They also indicate that technical talks are still being assembled even as the planned Swiss meeting has been delayed. The developments matter because the agreement is tied to ending the war in the Middle East and to the wider question of how Iran's nuclear activities will be monitored. Access for inspectors has long been a key issue in disputes over Iran's programme, particularly when the location of enriched material is uncertain.
Any arrangement involving the International Atomic Energy Agency would be closely watched by governments that want clearer verification of compliance. The briefing also comes against a backdrop of continuing scrutiny in Washington over the conduct of the conflict and the handling of military decisions. Senators are seeking to block travel funds for Defense Secretary Pete Hegseth until the Pentagon submits overdue reports to lawmakers, including an investigation into a deadly strike on an elementary school in Iran at the start of the US-Israeli war.
Officials have preliminarily said the United States was responsible for that strike, which was blamed on outdated intelligence. That debate adds to the political sensitivity surrounding the ceasefire implementation and the broader diplomatic process. For now, it remains unclear when the Switzerland talks will be rescheduled and what form the technical discussions will take.
It is also not clear how quickly the IAEA could gain access to Iranian sites or whether the reported side letter will satisfy all parties involved. The next developments will likely centre on whether the United States, Iran and the agency can agree on inspection terms that support the wider deal.
