The U.S. delegation is led by Vice President JD Vance and includes special envoy of U.S. President Donald Trump, Steve Witkoff, and son-in-law Jared Kushner. The Iranian delegation had already arrived earlier. The Iranian delegation is headed by Parliament Speaker Mohammad Baqer Qalibaf, accompanied by Foreign Minister Abbas Araghchi. This is the first meeting between the Iranian and American sides since the start of the war. Both sides have set conditions before the start of negotiations. Iranian officials have clearly stated that negotiations with the United States cannot begin until key conditions are met, primarily a ceasefire in Lebanon and the release of frozen Iranian assets. The U.S. has expressed concerns about nuclear weapons and the fate of transit through the Strait of Hormuz. Iran has previously reiterated that it will not relinquish control of this crucial transit route. As part of the preparations, security measures have been intensified and roads have been closed in Islamabad over the past few days due to the negotiations. Mohammad Baqer Qalibaf, who leads the Iranian delegation, said ahead of the talks that they have good intentions but do not trust the U.S. "Our experience in negotiations with the Americans has always been met with failure and broken promises," he said. U.S. Vice President JD Vance said the U.S. is entering the negotiations with a sense of optimism but warned Iran not to "play games." Peace negotiations between the U.S. and Iran are set to begin today in Islamabad. Speaking at a United Nations press conference on Friday, spokesperson for the Secretary-General Stephane Dujarric said that UN Secretary-General Antonio Guterres "calls on the parties to seize this diplomatic opportunity to engage in good faith toward a lasting and comprehensive agreement, with the aim of de-escalation and preventing a return to hostilities." Additionally, Lebanon and Israel have agreed to hold their first meeting on Tuesday at the U.S. State Department to discuss declaring a truce and setting a date for the start of negotiations.
