Iran’s Foreign Minister Mohammad Javad Zarif told reporters in New York that he has received no proposal about a possible participation of the United States in an upcoming meeting of the signatories of the nuclear deal to be held in New York.

Zarif who arrived for the United Nations General Assembly after uncertainty about receiving a U.S. visa, will meet representatives of Europe, Russia and China, the original signatories of the 2015 nuclear agreement. The U.S. withdrew from the accords in May 2018.

Iran’s chief diplomat told the official IRNA news agency it was the U.S. that pulled out of the deal and the negotiating table is open and “it was the Americans who left it”.

Asked if it is still possible for U.S. to join the meeting, Zarif said, “In the world of diplomacy nothing is impossible, but in the current conditions it does not appear arrangement can be made in the remaining few days.”

U.S. officials have not commented on the possibility of taking part in the upcoming meeting, which is expected to be at the level of foreign ministers.

Zarif also condemned the most recent U.S. sanctions against Iran’s Central Bank and its national reserve fund, saying “it is a sign of desperation” to sanctions entities that are already practically sanctions. He insisted that the sanctions are directed at the Iranian people who will not be able to get food and medicine.
