Iranian state media quoted a Foreign Ministry spokesman saying Sunday’s talks centered on ending the war, lifting sanctions and securing the release of Iran’s frozen funds.

Switzerland's foreign ministry said on June 22 it welcomed "constructive progress" in U.S.-Iran talks and is ready to support follow-up steps. It noted a joint statement by mediators Qatar and Pakistan and welcomed the "constructive progress" from intensive diplomatic talks on June 21-22 at Bürgenstock. The ministry said establishing a high-level committee under a memorandum of understanding is a "positive step" that will help plan the next political and technical phase, and that agreement on a roadmap to reach a final deal within 60 days creates conditions to begin technical-level discussions immediately. Switzerland said it will continue its mediation role and stands ready to assist.
