US and Iran Begin Four-Day ‘Lake Lucerne Summit’ in Switzerland Under Pakistan’s Mediation

BÜRGENSTOCK, Switzerland: Delegations from the United States and Iran met Pakistani mediators on Sunday ahead of the start of a four-day round of technical negotiations in Switzerland, aimed at advancing implementation of the Islamabad Memorandum of Understanding (MoU) and easing tensions in the Middle East.

The negotiations, informally dubbed the “Lake Lucerne Summit,” mark the first formal technical engagement between Washington and Tehran since the signing of the Islamabad MoU on June 17. The talks are expected to focus on translating the political framework into practical implementation measures.

The American delegation, led by US Vice President JD Vance and including senior envoys Steve Witkoff and Jared Kushner, first met with Prime Minister Shehbaz Sharif and Field Marshal Syed Asim Munir.

Before the meeting, Vance reportedly praised Pakistan’s diplomatic role in facilitating dialogue between Washington and Tehran and expressed appreciation for Islamabad’s mediation efforts.

Later, the Pakistani leadership held separate discussions with an Iranian delegation led by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi. Interior Minister Mohsin Naqvi also participated in the talks.

According to Pakistan’s Foreign Office, the Swiss negotiations include delegations from Iran, the United States and Qatar and represent the first direct follow-up to the Islamabad MoU. Islamabad reiterated its commitment to supporting the understandings reached between the two sides and emphasized that its facilitative role reflects a balanced and constructive diplomatic approach.

Officials noted that Pakistan hosted earlier rounds of contacts and maintained sustained diplomatic engagement throughout the crisis, efforts that eventually contributed to the signing of the memorandum.

The current round of talks follows the agreement signed electronically by US President Donald Trump and Iranian President Masoud Pezeshkian, with Prime Minister Shehbaz Sharif later signing the document as mediator.

The framework reportedly includes provisions related to maritime navigation, regional security, sanctions discussions and broader efforts to reduce tensions in the Middle East.

However, the negotiations are taking place against a backdrop of renewed uncertainty. On Saturday, Iran announced the closure of the Strait of Hormuz following Israeli military strikes in Lebanon, raising concerns about regional stability and global energy supplies.

The technical talks were originally scheduled to begin on Friday but were postponed after the escalation in Lebanon. Diplomats hope the four-day summit in Switzerland will help preserve momentum in the peace process and establish mechanisms for implementing commitments made under the Islamabad MoU.

Observers view the Bürgenstock negotiations as a crucial test of whether recent diplomatic breakthroughs can be transformed into a lasting framework for regional stability and conflict reduction.
