Vice President JD Vance announced that high-level discussions with senior Iranian officials in Switzerland created a "good foundation for a successful final deal" to end the US and Israel's war against Iran, which began in late February. Progress was reported on establishing mechanisms to keep the Strait of Hormuz open and to address the conflict between Israel and Iranian-backed Hezbollah in southern Lebanon, where a ceasefire appears to be holding. Mediators Pakistan and Qatar praised the "encouraging progress" made during the talks. The interim agreement, signed last week, sets a 60-day period for negotiating a permanent resolution. The US Treasury also issued a 60-day license, valid until August 21, waiving sanctions on Iranian oil, allowing its import into the US, a significant shift in policy since the 1990s. The waiver was announced by Treasury Secretary Scott Bessent, citing "ongoing productive talks in Switzerland." Iranian Foreign Minister Abbas Araghchi indicated "major progress to end the Lebanon War," while acknowledging that the effectiveness of the new mechanisms would be the "first real test" of the negotiations.

The talks, which began Sunday and extended into Monday, involved Vice President Vance, U.S. officials, Iranian parliamentary Speaker Mohammad Bagher Qalibaf, and Foreign Minister Abbas Araghchi. These discussions are part of a broader effort to address Tehran's nuclear program, a key issue in the conflict. Vance emphasized that the technical talks set to continue this week are crucial for building upon the established foundation. While acknowledging that a final deal, or "house," has not been built, Vance expressed confidence in the "successful foundation" laid for the American people.

The temporary suspension of sanctions on Iranian oil requires Iran to allow UN nuclear inspectors to return to the country. This commitment was highlighted by Vance as a "major milestone" and a "first step in permanently denuclearizing" Iran. The broader agreement also paves the way for some sanctions relief and the unfreezing of Iranian assets. Foreign Minister Araghchi noted that "Oil and petrochem exports are waived, blockade lifted, some frozen assets released, and major reconstruction & development plan launched for Iran." Despite these positive developments, President Donald Trump issued a social media warning, threatening to "hit Iran very hard again, only harder" if Iranian proxies in Lebanon, specifically Hezbollah, continue to cause trouble, adding a layer of complexity to the ongoing peace efforts. Meanwhile, Iran has increased crude oil shipments through the Strait of Hormuz, with approximately 6 million barrels on three supertankers transiting the strait, indicating a boost in activity following the interim agreement.
