U.S.-Iran negotiations end, technical talks will continue after Trump shakes talks with threats

U.S. Vice President JD Vance and senior Iranian officials arrived in Switzerland on Sunday to formally launch negotiations over Tehran’s nuclear program.

OBBUERGEN, Switzerland — High-level negotiations in Switzerland seeking a permanent end to the Iran war ended early Monday, with lower-level talks planned for the rest of the week as Iran and the United States agreed to create a “de-confliction cell” to address the fighting in Lebanon.

A statement from mediators Pakistan and Qatar said the cell would include the Lebanese government and would “ensure the adherence of the termination of military operations in Lebanon.” But it remains unclear whether that will be enough to stop fighting between the Iranian-backed militia Hezbollah and Israel, which occupies Lebanon and insists it must maintain a free hand to attack militants who are launching attacks into northern Israel.

The U.S. offered no immediate comment, while Iran praised the meditators’ work.

The talks marked the start of a 60-day diplomatic process that seeks to reach a permanent deal to end the Iran war. But the fighting in Lebanon remains one of the key sticking points.

Meanwhile, Iran insisted it had again shut the Strait of Hormuz over the weekend, the narrow mouth of the Persian Gulf crucial to energy shipments, while the U.S. said traffic continued.

Tense start to talks

The negotiations had a tense start Sunday in Switzerland, when Tehran took offense at U.S. President Donald Trump’s threat to attack and his warning that Iran’s president should watch what he says.

“Iran must immediately stop their highly paid PROXIES in Lebanon from causing trouble,” Trump said on social media. “If they don’t, we’ll hit Iran very hard again, just like we did last week, only harder!!!”

The comments from afar — on social media and to news outlets — complicated efforts by Vice President JD Vance and mediators Pakistan and Qatar to keep Iran engaged in discussions.

“They would do better to be careful about their statements,” Iran’s lead negotiator, Mohammad Bagher Qalibaf, said on X after Trump’s comments. “Our armed forces are prepared to respond to them in a different manner. They may keep talking, it is we who act.”

But later, Iranian Foreign Minister Abbas Araghchi wrote on X that “Tireless Pakistani and Qatari mediation has delivered major progress to end Lebanon War.” He said the first “real test” of negotiations would be whether the deconfliction cell succeeded in halting the fighting in Lebanon.

Vance and U.S. negotiators including Steve Witkoff and Jared Kushner, Trump’s son-in-law, had met with Qalibaf and Foreign Minister Abbas Araghchi for what Iranian state media said was about 80 minutes.

Pakistan and Qatar after the meeting said lower-level technical talks would continue in Switzerland for the rest of the week. Such talks aim at producing the breakthroughs needed for high-level officials to return and sign agreements.

A senior U.S. diplomat engaged in the talks, speaking on condition of anonymity to describe private discussions, said the talks Sunday included clarifying what Iran meant by recent statements about the Strait of Hormuz. Negotiators also discussed “mechanisms” to ensure the strait remains open and that a ceasefire in southern Lebanon is enforced, along with “robust” discussions on the nuclear issue.

Iran first wants to focus on Israeli strikes in Lebanon

Negotiators are in a 60-day sprint to reach an agreement on the technical details that hold massive implications for the world economy and global security.

“The question before us now is how much more can we accomplish together? Can we turn over a new leaf?” Vance said as the talks began, and asked whether they could “change relations in the Middle East permanently.”

The U.S. wants Iran locked into negotiations over its nuclear program amid concerns it may be used for military purposes, which Iran denies. Vance also wants Tehran to commit to keeping open the Strait of Hormuz, which Iran on Saturday claimed to close. The U.S. has disputed that, saying shipping traffic continued Sunday.

A renewed ceasefire in Lebanon, brokered on Saturday, appeared to be holding, and Israel’s military said it would lift movement restrictions for residents near the border with Lebanon on Monday morning — another sign of calm.

But neither Israel nor Hezbollah is a signatory to the U.S.-Iran deal, and Israeli Prime Minister Benjamin Netanyahu has vowed to keep his forces in southern Lebanon until any threat to Israel is eliminated. Hezbollah has refused to halt attacks unless Israel commits to withdrawing.

Sharp words are exchanged over Iran’s nuclear program

The agreement signed by Trump and Iranian President Masoud Pezeshkian immediately allows Tehran to sell its oil freely and paves the way for Iran to tap into billions of dollars in assets that are currently frozen. A member of Iran’s negotiating team told state television that draft wording was reached about “temporary sanctions waivers for oil and petroleum derivatives.”

The agreement also calls for Iran to dilute its stockpile of highly enriched uranium, believed to be buried under nuclear sites that were targeted in U.S. strikes a year ago.

Pezeshkian, however, declared Sunday that “we will never back down from the right to enrich uranium, and the other side is also forced to accept it,” according to Iran’s state media.

Trump, in a telephone interview Sunday with Fox News, warned that the Iranian president should watch what he says and threatened to take over the rest of the country, in comments relayed by a Fox correspondent.

Iran had cautiously approached the talks given its previous experience with U.S. negotiations on the nuclear issue, which twice in the past year were interrupted by military strikes.

The deal has stirred much controversy

Trump and Vance have come under searing criticism from parts of their own party for the deal, with Republican hard-liners unfavorably likening it to the nuclear agreement signed by the Obama administration that Trump and Republicans have insisted did nothing to terminate Iran’s nuclear program.

The new agreement says commercial vessels can pass through the Strait of Hormuz for 60 days without charge, but does not preclude future fees imposed by Iran. Trump made his own threat Saturday to levy U.S. tolls if there is no deal with Iran in 60 days, insisting that the money would be for “services rendered as the Guardian Angel to the countries of the Middle East.”

The Trump administration has been working to reassure global markets that the war has been merely a blip on oil prices, as Americans complain about high gasoline prices ahead of peak summer travel. After the deal was announced, oil futures dropped almost 8 per cent.
