The Iranian side is stalling amid apparent pressure on negotiators from the Islamic Revolutionary Guard Corps, according to an interlocutor familiar with the situation. They demand a firmer stance: no negotiations without lifting the U.S. blockade.
Pakistani, Egyptian, and Turkish intermediaries urged the Iranians to attend the meeting.
U.S. President Donald Trump stated earlier that he sent the Vice President to Pakistan for new talks regarding Iran. The delegation is "already heading there," Trump told journalists.
Jared Kushner and special envoy Steve Witkoff should also be included in it, according to him.
The main U.S. condition remains Iran's complete abandonment of any aspirations for nuclear weapons, according to Trump's version. He is even ready to personally meet with Iranian leaders if it helps reach an agreement, the U.S. president also stated.
Witkoff and Vance have already participated in negotiations with Iran in Pakistan. The round in April did not end with an agreement, although the parties spoke of some progress at the time, Reuters reported.
Iran is opening the Strait of Hormuz for the duration of the ceasefire between Lebanon and Israel adopted on April 16, Iranian Foreign Minister Abbas Araghchi reported on April 17.
At the same time, movement is possible only in coordination with the Islamic Revolutionary Guard Corps, and the future passage regime will depend on U.S. actions, Iranian officials clarified.
President Donald Trump later emphasized that, although the Strait of Hormuz was opened for commercial shipping, the U.S. will continue to block all maritime transport to or from Iranian ports.
