The sides agreed to establish a high-level committee to provide “political oversight of the negotiation process,” the mediators said in a joint statement.
The chief negotiators are expected to report regularly to the committee and lead working groups focused on “nuclear issues, sanctions, as well as a monitoring and dispute-resolution group to ensure the effective implementation” of a memorandum of understanding, along with other matters.
The sides also agreed on a “road map” for reaching a final agreement within 60 days.
Technical talks on “all issues” will continue in Switzerland through the end of the week.
The United States and Iran also agreed to create a “deconfliction group” involving Lebanon and mediated by Qatar and Pakistan to ensure an end to military operations in Lebanon.
Earlier, talks between the United States and Iran had reached an impasse after threats from U.S. President Donald Trump, an Iranian source told CNN.
Trump said in a phone call with Fox News that the United States could “take over” the Strait of Hormuz if no agreement with Iran is reached. He also threatened the Iranian delegation in Switzerland.
“Close it, and you won’t have a country. You won’t even get back to your f**king country,” Trump said, addressing Iranian diplomats.
U.S.-Iran talks in Switzerland
High-level negotiations between the United States and Iran began in Switzerland, with representatives of the mediator states, Qatar and Pakistan, also taking part.
U.S. Vice President JD Vance is leading the American delegation. President Donald Trump’s son-in-law, Jared Kushner, and special envoy Steve Witkoff are also part of the delegation.
Iranian Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi arrived in Switzerland late on June 20.
Iran’s joint military command, the Khatam al-Anbiya Central Headquarters, announced the closure of the Strait of Hormuz to all vessel traffic that day.
Tehran said the measure was prompted by what it described as U.S. and Israeli violations of the terms of a ceasefire agreement.
Trump later said the United States could impose fees on ships passing through the Strait of Hormuz if a final agreement with Iran is not reached.
