JERUSALEM (VINnews) — The Iranian delegation arrived in Switzerland for the expected negotiations with the United States, which are set to begin on Sunday at the Swiss resort of Bürgenstock. The talks come amid efforts to turn the recent memorandum of understanding between the two sides into a more detailed agreement covering nuclear, economic, and security issues.

Iran’s Foreign Ministry confirmed that the delegation includes Parliament Speaker Mohammad Bagher Ghalibaf, Foreign Minister Abbas Araghchi, Deputy Secretary of the Supreme National Security Council Ali Bagheri Kani, Central Bank Governor Abdolnaser Hemmati, Deputy Oil Minister Hamid Ford, Deputy Foreign Minister Kazem Gharibabadi, and Foreign Ministry spokesman Esmaeil Baghaei.

According to the Iranian Foreign Ministry spokesman, the delegation intends to discuss mechanisms for implementing U.S. commitments and the practical steps required from Washington in the next phase.

Baghaei stressed that Iran has fulfilled its obligations and expects the United States to carry out its commitments as well, including taking action to stop Israeli strikes in Lebanon, which Iran views as part of the existing understandings.

He added that “failure to implement commitments will jeopardize the understanding,” emphasizing that Iran’s policy is based on the principle of “commitment for commitment.”

The Iranian delegation’s arrival follows the arrival in Switzerland of U.S. envoy Steve Witkoff and Jared Kushner, while U.S. Vice President J. D. Vance departed Washington last night to participate in the expected meetings.

Before leaving for Switzerland, Vance expressed optimism about the possibility of progress in the upcoming talks, noting that his visit could last “only a day or two,” depending on the course of the negotiations and the outcome of the technical meetings.

He explained that Washington hopes to advance on two parallel tracks. The first concerns Iran’s nuclear program, while the second focuses on consolidating the ceasefire in Lebanon and preventing the collapse of the understandings reached in recent days.

Vance emphasized that the U.S. administration will work to prevent any new escalation in Lebanon and said that Washington seeks to prevent Israel from carrying out new strikes that could undermine the ongoing diplomatic efforts.

Pakistan’s Foreign Ministry also announced that negotiations will begin today with the participation of delegations from the United States, Iran, Pakistan, and Qatar. Pakistani Prime Minister Shehbaz Sharif and Army Chief Asim Munir are expected to join the talks.

Pakistan’s Interior Minister Mohsin Naqvi visited Tehran earlier this weekend and met with Araghchi, carrying messages encouraging progress in the negotiations and urging that they not be postponed.

This round of talks is considered the first real test of the memorandum of understanding signed by Washington and Tehran, amid international expectations over whether it can resolve disputes regarding Iran’s nuclear program, sanctions, and regional security arrangements within the 60-day deadline set for the negotiations.
