As the U.S. awaits the Iranian response to the draft agreement to end the war, Vice President Vance met Friday with one of the key mediators, Qatari Prime Minister Sheikh Mohammed Bin Abdul Rahman al-Thani.
Why it matters: While Pakistan has been the official mediator between the U.S. and Iran since the beginning of the war, the Qataris have continued working behind the scenes. The White House views them as especially effective in negotiations with Iran, U.S. officials say.
