Efforts to advance a diplomatic settlement between the United States and Iran suffered a setback after planned negotiations in Switzerland were cancelled, raising fresh concerns about the durability of the recently agreed ceasefire.
Swiss authorities confirmed that talks expected to take place at the Alpine resort of Burgenstock would no longer proceed, while Vice President JD Vance withdrew plans to attend the meeting alongside other American officials.
A White House spokesperson acknowledged the cancellation, saying arrangements surrounding the negotiations remained fluid and difficult to finalise. The US delegation had reportedly been prepared to travel once details were confirmed.
Iranian officials did not immediately comment on the development. Tehran had previously indicated a willingness to begin technical discussions following last week’s 14-point agreement, which extended a fragile ceasefire for an additional 60 days.
However, Iranian negotiators were said to be seeking evidence that Washington was implementing key aspects of the interim accord before committing to further talks. Reports from Iranian media suggested there had been no confirmation that Tehran’s delegation would travel to Switzerland.
Plans for a formal signing ceremony of the US-Iran agreement also appeared uncertain. While American officials had promoted the idea of an official event in Switzerland, Iranian authorities questioned the need for such a ceremony after both countries’ leaders had already endorsed the deal.
The conflict, which erupted in late February following US and Israeli military strikes on Iran, has claimed more than 7,000 lives, disrupted energy markets and fuelled economic uncertainty across the globe.
Questions over the agreement’s future have also been intensified by Israel’s position. Israeli leaders, who were not involved in the negotiations, have continued military operations against Hezbollah in Lebanon despite the broader ceasefire framework.
The agreement has generated debate in Washington, where several Republican lawmakers have criticised President Donald Trump’s administration for offering significant concessions to secure an end to the conflict.
Although Trump initially insisted the war would conclude only through Iran’s “unconditional surrender,” the final agreement includes sanctions relief, the release of frozen Iranian assets worth billions of dollars and waivers allowing Iranian oil exports to resume.
Iran’s Supreme Leader, Ayatollah Mojtaba Khamenei, described the deal as a product of American pressure to end the conflict and warned that future discussions regarding Tehran’s nuclear programme would remain difficult.
Under the agreement, negotiators have 60 days to reach a broader understanding on Iran’s nuclear activities, with provisions for an extension if necessary. The framework also establishes a $300 billion reconstruction initiative aimed at supporting recovery efforts in Iran and affected regions.
Meanwhile, the financial burden of the conflict continues to attract attention. Reports indicate the US Defence Department has requested roughly $80 billion to cover war-related expenses and other budgetary commitments.
Despite the agreement, several objectives originally outlined by Washington remain unresolved. Iran has maintained its longstanding position that it does not seek nuclear weapons while agreeing to international inspections and the dilution of highly enriched uranium stockpiles under monitoring arrangements.
US officials continue to express confidence that future negotiations could produce a more comprehensive nuclear accord. Critics, however, argue that Iran emerged from the conflict in a stronger strategic position after preserving influence over the Strait of Hormuz and securing economic concessions.
Iran has stated it will continue overseeing maritime activities in the Strait of Hormuz alongside Oman and plans to introduce new service charges for vessels transiting the crucial shipping route once the negotiation period concludes.
Oil prices eased on Friday as shipping traffic gradually resumed through the Strait of Hormuz, a vital corridor for global crude oil and liquefied natural gas exports.
In Lebanon, renewed Israeli airstrikes reportedly killed at least 15 people on Friday. Israeli authorities said the operations targeted Hezbollah positions, while the attacks added to concerns about the implementation of provisions calling for a permanent end to hostilities in the country.
The continued fighting has highlighted tensions between Washington and Israel, with President Trump increasingly critical of Israeli military actions despite longstanding ties between the two allies.
