US and Iran Begin High-Stakes Peace Talks in Islamabad Under Fragile Ceasefire

Apr 11, 2026

Iranian and US delegations meet in Islamabad for direct negotiations to end a six-week Middle East conflict, with Pakistan deploying over 10,000 security personnel and positioning itself as mediator through warm ties with all parties. China emerged as a critical guarantor whose intervention proved decisive in securing Iran's acceptance of the fragile two-week ceasefire, with Chinese Foreign Minister Wang Yi holding 26 calls during the conflict. Key disagreements remain over Lebanon's inclusion in the truce, which Pakistan and Iran support but Israel rejects, while Israel continues strikes targeting Hezbollah. Pakistani Prime Minister Shehbaz Sharif requested a ceasefire extension with White House approval as Trump publicly warned Iran of severe consequences if it does not reopen the Strait of Hormuz.
