US-Iran Talks in Switzerland Yield Progress, But Major Challenges Remain

On June 17, high-level negotiations between the United States and Iran in Lucerne, Switzerland, mediated by Qatar and Pakistan, achieved what was described as "encouraging" progress. The two sides signed a 14-point memorandum of understanding (MoU) establishing a de-escalation framework between Washington and Tehran, laying the groundwork for subsequent talks. The document was agreed upon after 12 hours of negotiations attended by senior officials from both countries.

US Vice President JD Vance led the Washington delegation, joined by President Donald Trump's son-in-law Jared Kushner and special envoy Steve Witkoff. On the Iranian side, Parliament Speaker Mohammad Bagher Ghalibaf led alongside Foreign Minister Abbas Araghchi.

High-level committee and new communication channels

A high-level committee was established to "politically oversee the reconciliation process," according to a joint statement by Qatar and Pakistan. The committee "agreed on a roadmap toward a final agreement within 60 days," with technical negotiations expected to continue over the next two months. The statement said: "The lead negotiators will report regularly to the High Committee and direct working groups focused on nuclear issues, sanctions, and a monitoring and dispute resolution group to ensure effective implementation of the MoU."

A new communication channel was also set up focusing on the Strait of Hormuz, aiming "to avoid incidents and misinformation, with the goal of ensuring the safety of commercial vessels transiting the Strait of Hormuz." This move comes as maritime traffic through this strategic waterway, which carries one-fifth of the world's oil and gas, continues to be disrupted. According to analysis by Windward, only 12 vessels crossed the strait over the weekend, a sharp drop from 35 crossings the previous day. Iran's de facto blockade of the strait has triggered a global energy crisis.

However, experts warn that the next phase of technical negotiations may be far more difficult than the initial political agreement and could take longer than 60 days. Major unanswered questions include whether Iran will be allowed to continue enriching uranium, the fate of its stockpile of highly enriched uranium, the scope of international inspections, and the roadmap for sanctions relief. Thomas Warrick, a senior fellow at the Atlantic Council, said: "The biggest issue is that removing or downgrading the enriched uranium could require several thousand people, including about 1,000 Americans, to enter some of Iran's most sensitive nuclear facilities." He argued that Iran is unlikely to accept this idea.

De-confliction cell for Lebanon

The agreement also includes the creation of a "de-confliction cell" to help "ensure compliance with the cessation of military activities in Lebanon." Iranian Foreign Minister Araghchi declared "major progress" in ending the war in Lebanon, but warned that the first test of the agreement would be the effectiveness of this cell.

This move comes as Israeli Prime Minister Benjamin Netanyahu announced Israel would maintain a presence in a security zone in southern Lebanon as long as necessary. The buffer zone established by Israel covers approximately 602 square kilometers (about 6% of Lebanese territory). In response, the head of Iran's Islamic Revolutionary Guard Corps Quds Force warned Israel to withdraw from southern Lebanon or face a repeat of the failure of its 2000 withdrawal.

Some analysts questioned the mechanism's impact in Lebanon. Joey Hood, a former senior US diplomat, noted that the Lebanese government and Israel were not directly involved in the talks that created the mechanism. "So, it gives Iran a veto over Lebanon... The MoU seems to say that we accept Iran's regional leadership role, including its proxy forces." Retired General Mark Kimmitt also argued that including Lebanon in the broader negotiations "complicates the matter enormously." Meanwhile, Al Jazeera correspondents reported "a cautious calm" in the Nabatieh area of southern Lebanon, as the ceasefire appeared to be holding after days of bloodshed.

Sanctions relief and frozen assets

Iranian Foreign Minister Araghchi also claimed that the agreement includes significant economic concessions from Washington, although the US has not publicly confirmed this. In a post on X, he said that sanctions on Iranian oil and petrochemical exports had been lifted, blockades removed, some frozen assets released, and a major reconstruction plan for Iran launched. He described these as Iran's main conditions having been met.

However, expert Warrick warned that implementing sanctions relief could face political difficulties in Washington, especially if congressional approval is required: "Congress is very unhappy with this agreement. And clearly, it's unlikely Congress will agree to lift some of the sanctions that Iran wants."
