The diplomatic push comes after Secretary Rubio said the Iran peace talks had made “slight progress,” while firmly rejecting Iran’s proposed Strait of Hormuz “tolling system.” Pakistan, as a nuclear-armed Muslim-majority country with relatively close ties to Washington, occupies a unique mediating position.

Analysts say Pakistan’s involvement reflects the urgency on all sides to reach an agreement. Core issues — including nuclear facility inspections and sanctions relief — remain unresolved.

A successful mediation could not only ease Middle East tensions but may also influence the trajectory of the $14 billion arms sale to Taiwan that the US paused due to the Iran situation.
