Iranian state media reported that Naqvi is expected to meet senior Iranian leadership during his trip.

Sources said he is likely to convey congratulations on the Islamabad memorandum of understanding (MoU) and discuss the next phase of cooperation.

Naqvi’s agenda in Tehran will focus on advancing and following up on negotiations between Iran and the United States, according to reports.

Pakistan has been playing an active diplomatic role as a mediator in facilitating dialogue between Tehran and Washington, which recently resulted in a memorandum of understanding aimed at ending the war.

The visit comes amid a shifting diplomatic environment following the cancellation of US-Iran talks in Switzerland.

The Swiss Foreign Ministry confirmed the cancellation of talks after US Vice President JD Vance postponed his planned travel to Switzerland for the negotiations.

The White House later said the United States remains hopeful that technical-level talks will begin soon.

US-Iran negotiations had been expected to address broader regional developments, but their postponement has added uncertainty to ongoing diplomatic efforts.
