The Swiss government announced on Friday, June 18, that negotiations scheduled to be held in Geneva and the mountain resort of Burgenstock between the United States and the Islamic Republic of Iran with the aim of reaching a final agreement have been postponed indefinitely.

The Swiss Foreign Ministry confirmed in its official statement that the planned talks between Washington and Tehran with international participation including Qatar and Pakistan have been postponed.

The Foreign Ministry indicated that Bern remains ready to facilitate these meetings as soon as the necessary preparatory work is completed, without setting a new date for their resumption.

American Cancellation

This critical diplomatic development coincided with the abrupt cancellation of US Vice President Jay DeVance's scheduled visit to Switzerland to meet with Iranian negotiators and begin to develop technical mechanisms to implement the Joint Framework Agreement. A White House spokesman said in a statement late that Vance and the U.S. delegation were ready to leave as soon as the finalization was finalized, adding that the logistical aspects of these negotiations had never been easy or predictable, while stressing the administration's aspiration to begin technical talks as soon as possible.

Tehran's conditions

Media circles in Tehran revealed that there were prior reservations among them about Lebanon that prevented the Iranian delegation from confirming the travel of the Iranian delegation to Swiss resorts to participate in the round of talks that were scheduled for today.

Iran's semi-official Tasnim news agency reported that Iranian negotiators had told the mediators of their urgent need to see concrete indications on the ground that the interim agreement was being implemented by the United States before engaging in any new rounds of negotiations.

The Iranian Foreign Ministry pointed out that holding a second official signing ceremony in Geneva is no longer a necessary step after the two countries' presidents signed the memorandum of understanding last Wednesday.

End the siege

U.S. forces have officially lifted the comprehensive naval blockade that had been imposed on Iranian ports throughout the conflict, as the first executive gesture following the remote signing of a memorandum of understanding by the U.S. and Iranian presidents to end the war. According to the terms of the agreement, the announcement of an immediate cessation of military operations on all fronts opens a 60-day extension deadline for negotiations to hold direct and complex talks between the two adversaries, whose diplomatic relations have been severed since 1979, including the formulation of final arrangements for Iran's nuclear file and the thorny file of economic sanctions.

European sources revealed that this abrupt postponement of direct technical negotiations in Switzerland reflects the crisis of mutual trust between Washington and Tehran, despite the major and historic diplomatic breakthrough achieved with the signing of the framework agreement last Wednesday, June 17, 2026.

The sources said that despite the Pentagon's actual step of lifting the naval blockade on Iranian ports on Thursday, the ambiguity surrounding the logistical aspects of the US side and Tehran's requirement for executive guarantees before sending its delegation puts the 60-day deadline allocated for the drafting of the final nuclear agreement to an early and very complex test, amid fears that this political stalemate will be reflected in a renewed deterioration on the field fronts linked to the two countries in the region.
