Pakistan's Asim Munir Due in Tehran to Revive Stalled US-Iran Talks

A return to Tehran after the June deal collapsed

Pakistan's army chief, Field Marshal Asim Munir, is expected in Tehran on Tuesday, October 20, 2026, for talks aimed at reviving diplomacy between Iran and the United States, more than three months after a peace arrangement brokered by Islamabad collapsed. The visit brings Pakistan's chief military negotiator back to a dispute centred on security guarantees and passage through the Strait of Hormuz.

A Pakistani official said Munir was due to make the trip, which Iranian media also described on Monday, October 19. Pakistan had not publicly announced the visit. His expected agenda includes meetings with Iranian officials on mediation, bilateral cooperation and regional security.

Munir helped negotiate the June Islamabad Memorandum of Understanding, which established a framework for further talks between Washington and Tehran. That arrangement broke down in July. Fighting in and around the Strait of Hormuz has continued while negotiations have remained stalled.

The journey comes at a difficult moment for Islamabad. Pakistan is trying to preserve access to Iran's leadership while meeting defence commitments to Saudi Arabia, where attacks by the Iran-backed Houthi movement have killed civilians. Pakistan has also recently suspended trade through two major crossings with Iran, adding an immediate economic problem to the diplomatic agenda.

Tuesday's meetings follow earlier summer discussions between Munir and Iranian leaders about preventing further escalation, reopening the strait and bringing the conflict to an earlier end. The same practical questions now confront the mediation effort: how to reduce fighting, restore shipping access and make another agreement last.

What the Islamabad memorandum was meant to achieve

The June memorandum created a negotiating framework rather than a completed settlement. Its planned discussions covered nuclear issues, sanctions and mechanisms for managing disputes, alongside the security questions generated by the war.

A framework agreement sets out what governments will negotiate and how they intend to proceed. The harder work comes in deciding the detailed obligations each side will accept, the order in which those obligations take effect and what happens if either government accuses the other of breaking its promises.

Washington and Tehran subsequently disagreed over security guarantees and arrangements for navigation through the Strait of Hormuz. Security guarantees are promises intended to reassure a government that accepting an agreement will leave it safer. Navigation arrangements concern whether ships can pass, under what conditions and with what protection.

Pakistan's earlier diplomatic effort had already shown how difficult it was to turn a pause in fighting into an agreement. During the April Islamabad talks, US Vice President JD Vance and Iranian Parliament Speaker Mohammad Bagher Ghalibaf held negotiations lasting 21 hours on April 11 and 12 without reaching a settlement. The June memorandum represented a later step, followed by another breakdown.

How the diplomatic effort reached this point

Pakistan has remained involved through successive rounds of diplomacy rather than entering the process only for Tuesday's visit. The sequence also shows how events outside the negotiating room have complicated efforts to restart talks.

• February 2026: The conflict involving the United States and Iran began.
• April 11 and 12: Senior American and Iranian representatives held talks in Islamabad that ended without an agreement.
• June: Washington and Tehran signed the Islamabad Memorandum of Understanding, brokered by Pakistan.
• July: The interim peace arrangement collapsed, with disagreements continuing over security and navigation.
• October 5: Operation Dawn of Yemen began amid fighting between Yemen's internationally recognised government and the Houthis.
• October 19: Munir's planned Tehran visit was reported as Russian Foreign Minister Sergei Lavrov also held meetings in the Iranian capital.
• October 20: Munir is expected to meet Iranian officials.

The summer talks provide the clearest indication of the immediate priorities: preventing a wider conflict, reopening the Strait of Hormuz and ending hostilities sooner. Tuesday's visit returns to those unresolved objectives.

Why the Strait of Hormuz remains central

The Strait of Hormuz connects Gulf energy exporters with international shipping routes. Roughly one fifth of the world's oil normally passes through the narrow waterway between Iran and Oman, making disruption there a concern for fuel importers far beyond the countries at war.

Munir's earlier summer meetings explicitly addressed reopening the strait. The continuing dispute involves both the physical safety of vessels and the rules governing their passage. A shipping company needs a route it can use reliably before committing its crews and cargo to a journey.

For people outside the region, the connection is straightforward: interrupted energy shipments can make fuel supplies less predictable and put pressure on transport and production costs. For the negotiating governments, restoring navigation is also tied to the wider security bargain, because shipping remains exposed while hostilities continue.

A proposal concerning Hormuz and a period of seven days has been under discussion, with Iranian Foreign Minister Abbas Araghchi receiving Washington's response in late September. The proposal's terms, Munir's possible role in carrying a further response and any date for renewed negotiations have not been publicly specified.

Pakistan and Qatar keep indirect channels open

Munir is one part of a broader Pakistani diplomatic effort. Prime Minister Shehbaz Sharif, Foreign Minister Ishaq Dar and Interior Minister Mohsin Naqvi have also exchanged messages with Iran's leadership in efforts to secure a lasting peace.

Pakistan has worked alongside Qatar and other regional partners to maintain communication between Washington and Tehran. Iranian officials describe Pakistan as the principal mediator, with messages also passing through Qatar.

Indirect diplomacy allows governments to communicate through another country when direct meetings are difficult. A mediator carries proposals, seeks clarification and returns responses. That work can continue even when formal negotiations have stopped, giving each side a way to explore possible terms.

Munir's involvement places a senior military figure within that process, alongside civilian diplomatic channels. His previous discussions with Iranian leaders give Tuesday's expected meetings continuity with the summer effort.

Lavrov's visit adds another diplomatic channel

Iranian President Masoud Pezeshkian met Russian Foreign Minister Sergei Lavrov on Monday, a day before Munir's expected arrival. The Iranian presidency said Pezeshkian welcomed initiatives involving regional countries on peace, security and development and favoured resolving regional problems through dialogue rather than military means.

Pezeshkian also blamed American interference and military presence for regional tensions. His position combines criticism of Washington with a stated willingness to consider diplomatic initiatives from countries in the region.

The consecutive visits place Russian and Pakistani officials in Tehran within a short period, each with a different relationship to the conflict. Pakistan's immediate task remains carrying proposals between Iran and the United States while discussing its own security relationship with Tehran.

Saudi defence commitments complicate Pakistan's role

Pakistan's mediation effort now runs alongside an increasingly urgent commitment to Saudi security. Houthi missile and drone attacks have targeted Saudi energy and aviation facilities during October, as fighting has intensified in Yemen.

Saudi Arabia's General Authority of Civil Aviation put the toll from the October 10 attack on Riyadh's King Khalid International Airport at 12 dead and more than 300 injured; another published tally put the deaths at 13. Dar said six Pakistani nationals were among the injured.

Pakistan's Saudi defence deployment follows a bilateral defence agreement signed in September 2025 and the Makkah Joint Defence Agreement with Saudi Arabia and Türkiye in August 2026. On October 5, the three governments agreed to deploy forces and capabilities rapidly under the latter arrangement.

Islamabad has described its contribution as defensive, with Saudi forces conducting combat operations. Meanwhile, the coalition supporting Yemen's internationally recognised government has provided air support for Operation Dawn of Yemen, which seeks to recover territory held by the Houthis.

Pakistan therefore has two demanding tasks at once: helping protect a defence partner and keeping a working relationship with Iran, which supports the Houthis. Those commitments make regional security a concrete part of Munir's Tehran agenda.

Border trade gives the visit an immediate local stake

Pakistan and Iran also face problems affecting businesses and communities along their shared border. Islamabad's Iran border trade suspension, ordered on October 16, interrupted commercial movement through Gabd-Rimdan and Taftan while passenger movement continued at Gabd-Rimdan.

The disrupted route reportedly handled more than 4,000 tonnes of liquefied petroleum gas daily. Former Quetta Chamber of Commerce and Industry president Ayoub Miryani said more than 2,000 containers were stranded at Gabd-Rimdan. Traders faced delayed deliveries, money tied up in cargo and the risk of losses on perishable goods.

Pakistani officials cited security, efforts to stop smuggling and changes to border administration. Iranian Foreign Ministry spokesperson Esmail Baqaei described technical problems and precautionary measures, with officials consulting over restoring normal operations.

Bilateral cooperation is on Munir's expected agenda, alongside shared concerns about Afghan stability, terrorism and regional energy connections. For border communities, progress in the relationship has an immediate meaning: safer travel, functioning crossings and the movement of food and fuel.
