US Vice President Vance Announces Iran Agrees to IAEA Nuclear Inspections After Switzerland Talks

The negotiations at Switzerland’s Burgenstock resort lasted about 18 hours, and Iran’s delegation was led by Parliament Speaker Mohammad Bagher Ghalibaf, according to U.S. officials’ account of the talks’ conclusion.
U.S.-linked reporting on why IAEA access is central cited Iran’s stockpile before the June 2025 U.S.-Israeli strikes: Iran held “440.9 kilograms of uranium enriched to 60 percent,” with only “around one percent” more enrichment work needed to reach weapons-grade levels; IAEA Director General Rafael Grossi estimated “more than 400 kilograms” of that material remained entombed at damaged facilities in Isfahan, Fordow and Natanz.
The U.S. military added a direct rebuttal to Iranian claims about Strait of Hormuz control: CENTCOM spokesman Navy Captain Tim Hawkins said, “Iran does not control the Strait of Hormuz,” adding “Traffic continues to flow, and U.S. forces are monitoring the situation,” and that there had been no significant reduction or repositioning of U.S. military assets in the region.
Iran’s position on shipping during the 60-day negotiation period was described as requiring coordination with Iranian authorities for transit while also not charging shippers fees during the talks—contrasting with warnings that the Strait could be disrupted.
Beyond inspection and deconfliction steps, the U.S.-Iran process included institutional follow-through: the parties created a “High Level Committee” to move negotiations forward, described by mediators Qatar and Pakistan as “positive” and “constructive.”
Vice President JD Vance announced Sunday that Iran has agreed to invite International Atomic Energy Agency inspectors back into the country, calling it a "major milestone" toward permanently ending Iran's nuclear program. The announcement came after an 18-hour negotiating session at the Bürgenstock resort in Switzerland, wrapping at 3:00 AM local time on June 22, according to Al-Monitor.
Mediators Qatar and Pakistan described a 60-day roadmap covering nuclear steps, sanctions relief, and keeping the Strait of Hormuz open. A new "High Level Committee" was created to carry the process forward. Coordination for an inspector visit could begin as soon as this week, Vance said.
Before the June 2025 U.S.-Israeli strikes on Iran, the IAEA reported Iran held 440.9 kilograms of uranium enriched to 60 percent. That is just "around one percent" more work away from weapons-grade levels. IAEA Director General Rafael Grossi now estimates "more than 400 kilograms" of that material remains buried under collapsed tunnels at facilities in Isfahan, Fordow, and Natanz, according to the IAEA.
U.S. B-2 bombers used Massive Ordnance Penetrators — the largest bunker-busting bombs in the U.S. arsenal — to seal those sites during the strikes. No inspectors have been inside since. Getting IAEA teams back in is the only way to verify whether any of that buried material has been moved or used.
Iran sent Parliament Speaker Mohammad Bagher Ghalibaf to lead its delegation, according to U.S. officials. Ghalibaf warned the U.S. to be "careful with their statements" after President Trump threatened on Truth Social to "hit Iran very hard" if Hezbollah caused trouble in Lebanon. The threat nearly derailed talks on the evening of June 21, according to The Jerusalem Post.
Iran's foreign ministry pushed back on the overall framing, saying real nuclear talks had not yet started. IRGC-linked outlet Fars News criticized the Iranian team for showing too much "flexibility," a sign of internal pressure on the delegation, according to ISW.
A financial proposal developed by Jared Kushner and Qatari officials would give Iran partial access to up to $24 billion of its roughly $100 billion in frozen assets. The catch: funds could only be spent on American agricultural goods — soy, corn, and wheat — with the U.S. keeping oversight of how money is used, according to AP.
The structure is designed to couple economic relief with verifiable compliance. Qatar's involvement as a co-designer also gives the mechanism a third-party buffer, making it harder for either side to walk away unilaterally. A separate oil sales waiver lets Iran sell crude — mainly to China — through August 21, 2026, according to The Guardian.
Iran has said ships must coordinate with Iranian authorities to transit the Strait of Hormuz, and plans to impose its own "maritime management fees" after the 60-day window closes. CENTCOM spokesman Navy Captain Tim Hawkins rejected that framing directly: "Iran does not control the Strait of Hormuz," he said. He added that "traffic continues to flow" and that U.S. forces are monitoring the situation, according to CENTCOM.
The numbers back that up. Some 55 merchant ships transited the Strait on June 20 alone, with roughly 17 million barrels of oil moving through daily. The U.S. confirmed no significant reduction or repositioning of military assets in the region. Lebanon remains the bigger flashpoint — a deconfliction cell covering Iran and the U.S. was created to prevent miscommunication, though Israel was excluded from that channel, according to Ynet News.
