The fragile diplomatic process launched by the United States and Iran after their landmark agreement to end months of conflict encountered its first setback Thursday, as planned follow-up talks in Switzerland were postponed amid uncertainty over the next phase of negotiations.
A Swiss Foreign Ministry statement confirmed that discussions scheduled for Friday at the Burgenstock resort would no longer take place. The announcement came after the White House said Vice President JD Vance had delayed a planned trip to Switzerland, where he was expected to meet Iranian negotiators to begin implementing the agreement reached this week between Washington and Tehran.
The deal, signed Wednesday by President Donald Trump and Iranian President Masoud Pezeshkian, formally ended a devastating five-week war and launched a 60-day diplomatic process aimed at addressing broader disputes, including Iran's nuclear program.
Despite the breakthrough, questions quickly emerged about how and when negotiations would proceed.
"The logistics of these negotiations have never been simple or predictable," a White House spokesperson said late Thursday. "As of now the Vice President is not departing tonight. We look forward to beginning technical talks as soon as possible."
