US Vice President JD Vance has postponed his planned visit to Switzerland as negotiations related to the US-Iran agreement remain uncertain.
The White House confirmed that Vance delays trip plans because the next phase of technical talks has not been finalized.
According to a spokesperson, the American delegation remains ready to travel whenever discussions are officially scheduled. However, officials said the negotiations involve complex logistics that continue to change.
The spokesperson added that Vance would not depart as originally planned. The administration said it would provide updates when concrete decisions are made.
The development comes after reports that Switzerland would host discussions on implementing a recently signed agreement between Washington and Tehran.
US authorities had earlier suggested that a formal ceremony could take place in Geneva. However, Iran questioned the need for another signing event. Iranian officials said the agreement had already been endorsed by both countries.
The latest delay shows that several issues remain unresolved despite recent diplomatic progress. Officials said Vance delays trip plans because both sides are still working on technical arrangements.
Iran has also expressed caution about moving ahead with further discussions. According to reports, Tehran wants proof that Washington is fulfilling its commitments under the interim agreement.
Iranian officials reportedly want evidence before advancing to the next round of negotiations. A report by Iran’s semi-official Tasnim news agency said there is no confirmed decision regarding an Iranian delegation visiting Geneva.
This uncertainty has slowed the process for both countries. The agreement between the United States and Iran is aimed at reducing tensions and creating a path for future cooperation.
Still, implementation remains a challenge due to political and logistical concerns. The current ceasefire extension has provided more time for diplomacy to continue.
Officials from both countries are expected to discuss technical details before moving toward larger commitments. For now, Vance delays trip plans until all necessary arrangements are in place.
The White House emphasized that the US delegation remains prepared to travel at short notice. Observers believe the coming days will determine how quickly negotiations move forward.
Despite recent diplomatic progress, both sides continue to proceed carefully. The future of the agreement will likely depend on trust, verification, and successful implementation of early commitments.
Until then, officials say discussions remain active but no final schedule has been announced.
