“The fourth round of indirect Iran-US negotiations is concluded; difficult but useful talks to better understand each other's positions and to find reasonable & realistic ways to address the differences,” Esmaeil Baqaei said in a post on his X account on Sunday afternoon.
“Next round will be coordinated and announced by Oman,” he added.
Iran and the US have held four rounds of talks since April 12, mediated by Oman, with the purpose of reaching a deal on Iran’s nuclear program and the removal of sanctions on Tehran.
