ISLAMABAD: Pakistan has recalled its advance diplomatic team from Switzerland, introducing fresh uncertainty into the next round of Iran-US negotiations following the recent Islamabad Memorandum of Understanding.

The decision comes as Tehran has expressed reluctance to proceed with talks at a European venue, according to multiple diplomatic sources familiar with the arrangements. Islamabad and Doha have emerged as the most likely alternative locations for the follow-up discussions.

Foreign Office spokesperson Mumtaz Zahra Baloch confirmed the recall of the technical team that had been dispatched to support preparations at the Bürgenstock Resort near Lucerne. “Pakistan remains fully committed to facilitating meaningful dialogue between the parties,” she stated, adding that logistical adjustments were being made in consultation with all stakeholders.

The development follows the electronic signing of the Islamabad MoU on June 17 by US President Donald Trump and Iranian President Masoud Pezeshkian. The agreement, mediated by Pakistan, established an immediate cessation of hostilities, reopened the Strait of Hormuz to maritime traffic, and initiated a 60-day negotiating window on sanctions relief and Iran’s nuclear programme.

Pakistani officials had been coordinating closely with Swiss authorities for the implementation talks originally scheduled for Friday. Senior diplomats from both Washington and Tehran, along with mediators from Pakistan and Qatar, were expected to participate.

Diplomatic sources indicated that Iran preferred venues perceived as more neutral and less influenced by Western European dynamics. “Tehran has conveyed its position clearly on venue preferences, prioritising locations with proven mediation track records,” one source said on condition of anonymity.

Pakistan’s role as the primary facilitator has been central throughout the process. The country hosted key rounds of talks in Islamabad earlier this year, including the April 11-12 discussions that laid groundwork for the recent breakthrough.

The Strait of Hormuz, through which nearly 20 percent of global oil and gas supplies transit, had been a major flashpoint during the recent conflict. The MoU’s immediate effect allowed resumption of tanker movements, easing pressure on international energy markets that had seen oil prices spike by over 25 percent at the height of tensions.

According to preliminary estimates from energy analysts, full reopening of the strait could add approximately 2.5 million barrels per day of Iranian crude to global supply within weeks, potentially stabilising prices around $70-75 per barrel in the short term.

Pakistan’s diplomatic efforts have drawn appreciation from multiple quarters. Chinese Foreign Ministry spokesperson Lin Jian welcomed Islamabad’s continued mediation, describing it as “constructive for regional stability.” Russia has similarly endorsed the process, urging adherence to the agreed timelines.

Foreign Minister Ishaq Dar held telephone conversations with his Swiss counterpart Ignazio Cassis in recent days, discussing the evolving situation. The two ministers reviewed progress on the broader peace push, with Switzerland maintaining its offer to host if conditions align.

The recall of the advance team, which included security and protocol personnel, reflects practical adjustments rather than any breakdown in talks. Preparations for alternative venues are understood to be advancing rapidly in both Islamabad and Doha.

Qatar, which has hosted preparatory meetings alongside Oman in previous phases, stands ready to support logistics. Doha hosted indirect discussions earlier in the process and maintains strong channels with both Washington and Tehran.

Market reactions in Pakistan remained measured. The Karachi Stock Exchange saw modest gains in energy and banking sectors on expectations of continued diplomatic momentum. The rupee held steady against the dollar amid positive sentiment around Pakistan’s elevated international profile.

Security arrangements in potential host cities are being reviewed. Islamabad has already tightened protocols in key diplomatic zones following earlier rounds of high-level engagements.

Background to the current phase traces back to Pakistan’s sustained mediation efforts since early 2025. Multiple rounds in Oman, Switzerland, and Pakistan itself have gradually built channels of communication between the long-time adversaries.

The 60-day clock for finalising a comprehensive agreement on Iran’s nuclear programme and sanctions architecture is now underway. Key issues include verification mechanisms for uranium stockpiles, estimated at around 440kg of highly enriched material, and phased sanctions relief that could unlock billions in frozen assets for Tehran.

Analysts note that venue decisions carry symbolic weight in such sensitive negotiations. European locations have traditionally hosted nuclear-related talks, including earlier JCPOA discussions, but current geopolitical sensitivities have prompted a reassessment.

Pakistani officials have emphasised continuity. “Our focus remains on substance over location,” a senior diplomat remarked. The country has invested significant political capital in the process, with Prime Minister Shehbaz Sharif personally engaging key leaders.

Regional implications extend beyond bilateral US-Iran dynamics. Stability in the Gulf affects Pakistan’s energy imports, remittances from the Middle East, and broader security environment along its western borders.

The next few days are expected to bring clarity on the venue and exact timing for the resumed talks. Both sides have signalled willingness to continue dialogue within the agreed framework, though sticking points on implementation details persist.

Observers suggest that successful conclusion of the current phase could open pathways for wider regional de-escalation, including reduced proxy tensions and economic normalisation.

Pakistan’s facilitation has positioned it as a credible bridge in a complex geopolitical landscape. As one of the few nations maintaining functional relations across divides, its role underscores the value of quiet diplomacy in high-stakes conflicts.

Future developments will likely hinge on technical working groups addressing verification protocols and sanctions timelines. The involvement of the International Atomic Energy Agency is anticipated for monitoring commitments.

The situation remains fluid, with all parties engaged in behind-the-scenes coordination to keep the process on track. Islamabad continues to coordinate closely with Washington, Tehran, Doha, and Bern to identify the most viable path forward.
