U.S. Vice President JD Vance and Iranian chief negotiator Mohammad Baqe arrived in Switzerland on June 21 [1] for high-level peace talks.

The meetings represent a critical attempt to find a durable end to the conflict between the two nations and resolve long-standing disputes over Tehran’s nuclear program. The diplomatic effort occurs as tensions escalate over maritime access to one of the world's most vital shipping lanes.

Negotiators are meeting at the Bürgenstock resort [1], though some reports placed the talks in Zurich [2]. The arrival of the delegations was reported as occurring between June 20 [2] and June 21 [1].

Concurrent with the diplomatic outreach, Iran said it had closed the Strait of Hormuz. Tehran said this move was intended to pressure the United States during the negotiations [3].

United States officials disputed the Iranian assertion. U.S. Central Command said Iran does not control the Strait of Hormuz [3]. The dispute over the waterway adds a layer of volatility to the summit as both nations seek to balance diplomatic concessions with strategic leverage.

The talks aim to establish a framework for peace that addresses regional security, and the technical specifics of Iran's nuclear capabilities [3]. While the U.S. seeks a verifiable reduction in nuclear activity, Iran has linked its cooperation to the lifting of sanctions and the recognition of its regional interests.

The simultaneous pursuit of diplomacy and the strategic threat to the Strait of Hormuz suggests a 'carrot and stick' approach by Tehran. By claiming control over a primary global oil transit point while engaging in peace talks, Iran is attempting to increase its bargaining power regarding nuclear sanctions. For the U.S., the challenge lies in securing nuclear commitments without appearing to succumb to maritime brinkmanship.
