Talks began around 15:00 local time on June 21, paused for internal consultations, and then stalled after Iran refused to return while mediators from Qatar and Pakistan kept trying to bridge the gap.
Iran’s negotiating team left talks in Switzerland after a brief first session and refused to return following what Iranian sources described as threatening remarks by Trump. The talks began around 15:00 local time on June 21 and paused after about 1.5 hours for a 30-minute internal consultation break. Iran then declined to resume the meeting, while Qatar and Pakistan continued mediation efforts. Iranian sources also said Tehran protested alleged U.S. breaches and demanded asset unfreezing and sanctions waivers for oil exports, underscoring both the immediate breakdown in the discussions and the wider disputes still separating the two sides.
