High-level delegations from the United States and Iran have convened in Burgenstock, Switzerland, for crucial talks aimed at implementing a provisional peace agreement. US Vice President JD Vance leads the American contingent, which also includes special envoy Steve Witkoff and Jared Kushner, son-in-law to President Donald Trump. Vance expressed hopes for progress on both the nuclear issue and a ceasefire in Lebanon, stating that these are the "two big things" for discussion during the anticipated couple of days of talks. The talks are a follow-up to a Memorandum of Understanding (MoU) signed electronically by President Trump and Iranian President Masoud Pezeshkian on Thursday, mediated by Pakistan and Qatar.

The Iranian delegation, led by Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, arrived with the stated goal of ensuring all parties fully implement the interim deal. However, Iran's Islamic Revolutionary Guard Corps (IRGC) announced the closure of the Strait of Hormuz on Saturday, accusing Israel of violating the ceasefire in Lebanon. This move, which impacts a vital waterway for about a fifth of global oil supplies, complicates the discussions, although the US military asserted the strait remained open for commercial traffic. The closure was made by Iran "in light of America's bad faith and blatant breach of the first clause of the war-ending memorandum of understanding, and in response to the relentless and continuous violation of the ceasefire by the Zionist regime in southern Lebanon.

The negotiations, originally scheduled to commence on Friday, were delayed due to heightened tensions, including intensified Israeli attacks in Lebanon that killed dozens on Saturday, despite a reported ceasefire with Hezbollah. While Israel maintains it is not a party to the US-Iran deal, it has pledged to act against threats and keep forces in Lebanese territory it occupies. Mediators Pakistan and Qatar, represented by Prime Minister Shehbaz Sharif and Field Marshal Asim Munir, and Prime Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani respectively, have joined the talks to help navigate these complexities, aiming for a durable resolution to the nearly four-month-long conflict that has seen oil prices soar above $100 per barrel and rattled international markets.

The US-Iran talks are expected to span 60 days, during which officials will address the final phase of the peace process and resolve major sticking points, such as Iran's nuclear program and the ongoing conflict in Lebanon. The interim agreement allows Iran to sell its oil freely and access billions of dollars in frozen assets. While the agreement specifies that commercial vessels can pass through the Strait of Hormuz for 60 days without a charge, the long-term implications for global energy markets remain a critical topic of discussion and potential contention.
