Director General of the International Atomic Energy Agency (IAEA), Rafael Grossi, said on Saturday he had “constructive discussions” with Iranian officials that could pave the way for the revival of a landmark 2015 agreement, AFP reported.

“By constructive discussions that we are having now, and by good agreements, I’m sure we are going to be paving the way for important agreements,” Grossi said in a news conference in Tehran alongside Mohammad Eslami, director of Atomic Energy Agency of Iran.

Grossi arrived in Tehran on Friday to hold talks with senior Iranian officials with technical nuclear issues high on the agenda. 

The IAEA chief is also due to hold talks with Iranian President Ebrahim Raisi during his two-day visit.

Grossi was greeted at the airport by Behrouz Kamalvandi, the AEOI spokesman, upon his arrival and rushed to meet the Iranian nuclear chief Mohammad Eslami.

The details of their talk are not known yet.

This is Grossi’s fourth visit to Iran since assuming office in December 2019 and comes ahead of the IAEA Board of Governors meeting on Monday.

Iran and the IAEA are at odds over several issues concerning the country's nuclear activities. The UN nuclear watchdog said in a confidential quarterly report that it had detected particles of uranium enriched to 83.7 percent during an inspection of the Fordow nuclear facility on January 22.

On Wednesday, Eslami rejected the accusation, asserting that there has been “no deviation” in Iran's peaceful nuclear activities.

Grossi's visit may help break the deadlock in negotiations on the restoration of the 2015 nuclear deal, the Joint Comprehensive Plan of Action (JCPOA).
