Vance's serious participation in indirect negotiations with Iran Vance has been actively involved in indirect negotiations with Iran in the past two weeks. Those efforts began two weeks ago, when Vance sent a letter to Mosen Razai offering direct talks. Vance also spoke almost daily with mediators involved in the Iran-US negotiations, including Qatar's prime minister, Sheikh Mohammed bin Abdulrahman Al Thani, and Pakistan's army chief of staff, Asim Munir. Through Qatari and Pakistani mediators, Vance discussed the possibility of an expert-level technical meeting between Iran and the United States in the near future, although no date has yet been set.
