Iran-U.S. Negotiations Fail to Reach Agreement

U.S. Vice President JD Vance led a delegation in 14-21 hours of high-level face-to-face talks with Iran in Islamabad, Pakistan (allegedly the highest level in nearly 50 years), but ultimately failed to reach a ceasefire or peace agreement.
Core disagreements: Iran's nuclear weapons development, navigation rights in the Strait of Hormuz, Hezbollah in Lebanon, and other issues. The U.S. claims to have proposed a "final, best plan," while Iran is unwilling to fully abandon nuclear-related activities.
Vance stated that the negotiations have broken down, but expert teams on both sides will continue to communicate through text exchanges, and Pakistan will continue to mediate.
Background: This is part of the ceasefire negotiations related to the Iran war in 2026. Currently, a fragile ceasefire is being maintained, but there are still casualties from Israeli airstrikes in southern Lebanon. Saudi Arabia also announced the restoration of the East-West oil pipeline previously affected by Iranian attacks, returning to a capacity of 7 million barrels per day.
The situation in the Middle East remains uncertain, and oil prices and the global energy market may be affected.
