“I’m travelling to Tehran today for meetings with Iranian officials to address outstanding questions in Iran,” Grossi wrote on Twitter on Monday.
“I hope to establish a fruitful and cooperative channel of direct dialogue so the IAEA can resume essential verification activities in the country,” the head of the UN’s atomic agency added.
Tehran has expressed hope Grossi’s visit would be “constructive”.
Grossi was expected to meet Foreign Minister Hossein Amir Abdollahian and Mohammad Eslami, the chief of Iran’s Atomic Energy Organization (AEOI).
Iran has stopped observing some conditions of the Joint Comprehensive Plan Of Action (JCPOA) in 2019, after the United States withdrew from the plan in 2018 under then President Donald Trump and began imposing sanctions on Tehran.
Representatives of Tehran and the other signatories of its 2015 nuclear deal will be in Austria starting November 29 to try to restore the Iran nuclear deal.
