High-level diplomatic efforts between the United States and Iran have transitioned into a multilateral phase in Switzerland, with Pakistan and Qatar now actively mediating. Vice President JD Vance joined U.S. envoys Steve Witkoff and Jared Kushner in Zurich on Saturday to prepare for formal sessions starting Sunday. The Iranian delegation, led by Foreign Minister Abbas Araghchi and Parliament Speaker Mohammad Bagher Ghalibaf, has also arrived, signaling Tehran’s intent to leverage regional developments to ensure the U.S. fulfills prior commitments. The negotiations have evolved into a complex three-track crisis involving maritime security in the Strait of Hormuz, the enforcement of a ceasefire in Lebanon involving Hezbollah, and the long-standing nuclear file. While the Iranian Revolutionary Guard Corps (IRGC) claimed to restrict traffic in the Strait of Hormuz as pressure regarding Israeli actions in Lebanon, U.S. Central Command (CENTCOM) maintains the waterway is open, reporting that 55 commercial vessels transited safely on Saturday. President Donald Trump has entered the maritime dispute by asserting there will be "NO TOLLS" in the strait during the current 60-day ceasefire period. However, the President warned that the U.S. may consider imposing its own tolls should a final agreement fail to materialize. This administrative push aims to link the nuclear implementation timeline directly to the cessation of hostilities in Lebanon, effectively giving negotiators 60 days to finalize a comprehensive accord.
