According to CNN, on June 21 local time, on the eve of the US-Iran talks, Vice President Viscer called for a ‘fundamental change’ in US-Iran relations.
On that day, Vance gave a speech before the talks with the Iranian side. He said, "The leaderships of the United States and Iran have never held such a high-level meeting. President Trump has instructed us to open a new chapter in our bilateral relations, to reshape the relationship between the United States and the Iranian people, and to extend an offer of reconciliation to Iran."
He added, “We want to make it clear to Iran that as long as the Iranian leadership ceases to be a source of regional turmoil and permanently abandons its nuclear ambitions, the United States is willing to see a fundamental change in bilateral relations with Iran. This is undoubtedly our goal.”
"Just a few hours ago, we achieved significant progress. I believe that in the coming time, both sides can make further breakthroughs." Wan said.

On June 21 local time, American and Iranian delegations began negotiations in Bielenberg, Switzerland. This is the first round of talks after the signing of a memorandum of understanding between the two countries.
The Iranian delegation included Iran's Foreign Minister Alaa'ghazi and others. On the American side, Vice President Williams, Presidential Envoy Whitlock, and Trump's son-in-law Kushner participated in the negotiations. Pakistan and Qatar attended as mediators.
According to Bahae, a spokesman for the Iranian Ministry of Foreign Affairs, this round of talks will last for one day. On the morning of the 21st, the Iranian delegation will have separate meetings with the mediating countries, Pakistan and Qatar. In the afternoon, a four-party meeting will be held between Iran, the United States, Qatar, and Pakistan.
He emphasized that all discussions during this round revolved around ensuring the implementation of the memorandum. Article 13 of the memorandum clearly stipulates that there are prerequisites for initiating final agreement negotiations, and five key provisions must be fulfilled first. The first of these provisions is a complete ceasefire on all fronts, including those in Lebanon.
Iran believes that this clause has not been fulfilled so far. It accuses the US of either being unable to restrain the relevant parties from fulfilling the obligations, or having no intention of fulfilling the commitments. At the same time, it points out that Israel continues to violate the agreements contained in the memorandum.
"This is the core point of disagreement at today's meeting."
