The United States and Iran met for their first direct round of negotiations on June 21, 2026, at the Bürgenstock resort near Lucerne, Switzerland, to discuss ceasefire and nuclear matters [1, 2, 3, 4, 5, 6]. The talks had been postponed from June 19 due to escalation of fighting between Israel and Lebanon and logistical issues affecting US Vice President JD Vance [7, 8, 2, 4, 6].
A 14-point memorandum of understanding signed last week commits both countries to reopening the Strait of Hormuz and ending hostilities on multiple fronts, including Lebanon [9, 6]. US Vice President Vance confirmed Iran agreed to allow UN nuclear inspectors back into the country as part of the agreement, calling it "a major milestone for the American people and a first step in permanently... ending a nuclear weapons programme in Iran" [9]. Vance also said President Trump "asks us to turn a new page, rebuild our relationship with the Iranian people, and reach out a hand if their leadership stops inciting regional instability and abandons nuclear weapons ambitions" [4].
Iran insists its nuclear program is peaceful and refuses to give up uranium enrichment but has offered written guarantees not to pursue nuclear weapons [9, 4, 10, 6]. The main agenda items in the talks include Iran’s nuclear program, reopening the Strait of Hormuz, and achieving a ceasefire—all especially focused on Lebanon where Israel's conflict with Hezbollah has escalated recently, causing casualties on both sides [4, 6].
On June 20, Iran announced it was closing the Strait of Hormuz in response to Israeli military actions in Lebanon, although about 55 commercial ships reportedly passed through safely that day [4, 10, 6]. US officials deny the strait is fully closed [10]. US President Donald Trump warned on social media that the US would impose tolls on the strait if the deal fails and threatened stricter attacks on Iran over its proxy activity in Lebanon [4, 10, 11, 6]. During the Switzerland talks on June 21, Iran's chief negotiator Mohammad Bagher Ghalibaf suspended negotiations after Trump's threatening posts, warning the US to "be cautious" and stating, "our armed forces are ready to respond in another way" [10, 11, 5, 6]. Despite the suspension, US negotiators including VP Vance reportedly continued working overnight [11, 5].
Mediators Qatar and Pakistan announced on June 22 the formation of a high-level committee to supervise the talks and a technical roadmap aiming to complete a final peace deal within 60 days [9, 5, 6]. The 60-day timeline was confirmed in the original ceasefire memorandum remotely signed by Presidents Trump and Pezeshkian on June 17 [9, 8, 6]. That agreement also proposed a $300 billion fund for rebuilding Iran [6].
The next scheduled step is continued technical talks overseen by the new supervisory committee, tasked with reaching a final agreement within the 60-day period starting mid-June.
