U.S. and Iran End 18-Hour Switzerland Talks with Initial Agreements, but Major Disputes Remain

The first round of direct high-level talks between the United States and Iran concluded after nearly 18 hours of negotiations in Bürgenstock, Switzerland. The talks, mediated by Qatar and Pakistan, marked the first major diplomatic contact between the two sides as they seek to address regional tensions and Iran's nuclear program.

Vance Reaffirms U.S. Position on Iran's Nuclear Program

Before negotiations began, U.S. Vice President JD Vance reaffirmed that preventing Iran from acquiring nuclear weapons remains Washington's top priority.

"If Iran is willing to permanently abandon its ambition to develop nuclear weapons, the United States is prepared to fundamentally change its relationship with Iran," Vance said.

Vance also expressed confidence that meaningful progress could be achieved if Iran demonstrates a genuine willingness to abandon its nuclear weapons ambitions.

Iran Repeatedly Presses Israel's Lebanon Operations

Iran maintained a hardline position throughout the negotiations, repeatedly insisting that Israel's ongoing military operations in Lebanon be addressed before discussions on other major issues could move forward.

"Lebanon is one of the principal fronts where an end to the war must be declared. If the Lebanon issue is not resolved, the remaining topics clearly will not move forward," Iranian negotiator Hossein Ghorbanzadeh said.

According to reports, tensions rose during the talks after Iran objected to comments made by President Donald Trump. Negotiations briefly stalled before mediators Qatar and Pakistan resumed indirect discussions between the two delegations.

Initial Agreements Reached

Following the conclusion of the talks, Qatar and Pakistan released a joint statement outlining several preliminary agreements.

• The United States, Iran, and Lebanon agreed to establish a deconfliction mechanism intended to help maintain a ceasefire and reduce the risk of renewed military escalation in Lebanon.
• The parties agreed to guarantee the safe passage of commercial vessels through the Strait of Hormuz for the next 60 days while establishing direct communication channels to reduce the risk of maritime incidents.
• The United States and Iran agreed to establish a high-level committee to supervise working-level negotiations on Iran's nuclear program, sanctions relief, and implementation of future memorandums of understanding.

Technical Talks Continue

Iranian officials welcomed the outcome of the negotiations, claiming progress had been made toward draft agreements involving oil sanctions relief, temporary sanctions exemptions, and the easing of certain maritime and financial restrictions. Those claims have not been independently confirmed by U.S. officials.

Technical teams from both countries will remain in Switzerland throughout the week to continue working-level negotiations under the supervision of the newly established high-level committee.

Major Obstacles Still Unresolved

Despite the preliminary agreements, the most difficult issues remain unresolved. Washington continues to demand that Iran permanently abandon its nuclear weapons ambitions, while Tehran insists that Israel's military operations in Lebanon must be addressed before broader negotiations can move forward. Those competing positions are expected to remain the primary obstacle in the next phase of talks.
