"Grossi will arrive in Tehran on Monday," Behrouz Kamalvandi, the spokesman of the Atomic Energy Organization of Iran (AEOI) told national TV.
Grossi's trip takes place just before next week's meeting of the IAEA’s 35-nation Board of Governors.
Western members of the board scrapped plans in September for a resolution criticizing Iran after the Islamic Republic and the UN nuclear watchdog reached an agreement on Sept. 12 over prolonging monitoring of some nuclear activities in Iran and Tehran invited Grossi to the country for talks on outstanding issues, Reuters reported.
Iran has repeatedly warned the IAEA against adopting politically-motivated stances through “biased reports” on the country’s nuclear program, emphasizing such moves will undermine the constructive process of cooperation between the two sides.
Kamalvandi said Grossi will meet Iran's Foreign Minister Hossein Amir-Abdollahian and Iran's nuclear chief Mohammad Eslami during his visit.
On Monday Iranian Foreign Ministry spokesman Saeed Khatibzadeh said Grossi has had “close consultations” with both the AEOI and the Iranian Embassy in Vienna in response to the IAEA chief’s latest remarks, in which he complained that he had “no contact” with the new Iranian government.
Iran and the remaining parties to the JCPOA – China, Russia, Britain, France and Germany – have held six rounds of talks in Vienna since April in order to revitalize the unraveling accord by bringing the US back to compliance three years after it withdrew from the pact and reimposed and reinforced sanctions on the Islamic Republic.
A new round of talks will resume in the Austrian capital on November 29.
Meanwhile, Grossi on Wednesday denied IAEA’s cameras played a part in a June attack on an Iranian nuclear facility, after Tehran said it was investigating the possibility.
The director general “categorically rejects the idea that the agency’s cameras played a role in assisting any third party to launch an attack on the TESA Karaj complex,” an IAEA report said, according to AFP.
Iran has told the IAEA that "its security and judicial authorities' were investigating whether the terrorists have used the agency’s cameras” to launch the attack on the complex, the report said, referring to the site near the city of Karaj, about 50 kilometers from the capital Tehran.
