U.S. Vice President JD Vance held talks with Pakistani Prime Minister Shehbaz Sharif on Saturday (April 11), the White House and Sharif's office said ahead of negotiations with Iran seeking to end their six-week-old war, Reuters reports.
Tehran however threw the talks into doubt by saying they could not begin without commitments on Lebanon and sanctions.
US Special envoy Steve Witkoff and President Donald Trump's son-in-law Jared Kushner were also taking part.
"Prime Minister expressed the hope that these talks would serve as a stepping stone toward durable peace in the region," Sharif's office said.
These will be the highest-level U.S.-Iran talks since the Islamic Revolution of 1979 and the first official face-to-face negotiations between the two sides since 2015, when they reached a deal on Iran's nuclear program.
