TEHRAN, APR 18: No date has been set for the next round of negotiations between Iran and the United States, Iran’s deputy foreign minister said on Saturday, adding that a framework of understanding must be agreed first.

The highest-level US-Iran talks since the 1979 Islamic Revolution ended in Islamabad without agreement last weekend.

US President Donald Trump has told Reuters there would probably be more direct talks this weekend, though some diplomats said that was unlikely given the logistics of convening in Islamabad, where the talks are expected to take place.

“We are now focusing on finalising the framework of understanding between the two sides. We don’t want to enter into any negotiation or meeting which is doomed to fail and which can be a pretext for another round of escalation,” Saeed Khatibzadeh told reporters on the sidelines of a diplomacy forum in the southern Turkish province of Antalya.

“Until we agree the framework, we cannot set the date… There was significant progress made, actually. But then the maximalist approach by the other side, trying to make Iran an exception from international law prevented us from reaching an agreement,” he said, referring to US demands over Iran’s nuclear programme.

“I have to be very crystal clear that Iran would not accept being an exception from international law. Anything that we are going to be committed to will be within the international regulations and international law.”

Asked about reports that Iran again closed the Strait of Hormuz on Saturday after its temporary reopening following a separate US-brokered 10-day ceasefire between Israel and Lebanon on Thursday, Khatibzadeh said Iran had announced it would allow the safe passage of commercial vessels in line with the terms of the truce.

“The other side, the American side, tried to sabotage that by saying that it is open except for Iranians. So that was the reason we said that ‘if you are going to violate the ceasefire terms and conditions, if Americans are not going to honour their words, there will be repercussions for them’,” he said.
