US vice president JD Vance has withdrawn from a planned trip to Switzerland, where he had been expected to meet Iranian negotiators for talks on implementing the recently signed US-Iran peace agreement, according to the White House.
The talks, which were expected to begin in Geneva on Friday, were aimed at working through the technical details of the 14-point accord reached by Washington and Tehran to end months of conflict between the two countries.
A White House spokesperson said the US delegation had been prepared to travel as soon as arrangements for the negotiations were finalised.
"But the logistics of these negotiations have never been simple or predictable," the statement said.
The development comes amid uncertainty over the next phase of diplomacy.
While US officials had signalled plans for a formal signing ceremony in Geneva, Iran's foreign ministry questioned the need for such an event after the agreement was already signed by both countries' presidents on Wednesday.
Iran has also indicated that it wants to see evidence that Washington is implementing the interim deal before committing to further negotiations. Iranian media reported earlier that Tehran had not yet confirmed whether its delegation would travel to Geneva.
The diplomatic wrangling raises fresh questions about the durability of the ceasefire agreed between the two sides and the prospects for a lasting settlement after a conflict that has killed thousands, disrupted energy markets and rattled the global economy.
