The head of Iran’s Atomic Energy Organization, Ali Akbar Salehi, told reporters there is a chance that Iran could call for a meeting of the foreign ministers of the P5+1 during the United Nations General Assembly in September. The meeting would be the first between Iranian Foreign Minister Mohammad Javad Zarif and US Secretary of State Rex Tillerson, should both attend.

Zarif met numerous times with Tillerson’s predecessor, John Kerry, and the two broke a decadeslong taboo with direct, bilateral negotiations. The Iran-US bilateral meetings were largely responsible for breaking the impasse over Iran’s nuclear program.

Salehi also discussed the possible Iranian response to a US withdrawal from the nuclear deal that was signed two years ago between Iran and the five permanent members of the United Nations Security Council plus Germany. He said that if the United States and the European countries in the P5+1 leave the deal, Iran will do so as well. But he said that if the other members of the P5+1 remain and only the United States leaves the deal, Iran will not walk away.

Salehi said the US desire to walk away from the nuclear deal has more to do with domestic political circumstances in the United States. “In its political strategy, the US is conflicted … [and] we are seeing political confusion and some regional countries are escalating this mess,” Salehi said, without elaborating. He said Iran has made preparations for “all possible scenarios,” but hopes the United States “comes to its senses.”
