Eslami stated on the sidelines of a cabinet meeting in Tehran on Wednesday claims that Iran has reduced its obligations are pointless when it comes to the NPT as Tehran is committed to the non-proliferation regime. He noted that Tehran has no unfulfilled obligations in this regard.

The AEOI chief has described such allegations as part of a psychological warfare against Iran.

The Iranian official stressed that any visit by the head of the IAEA to the country needs to have a "specific objective".

Grossi last week announced that he intends to go to Tehran in February for "much-needed dialogue" over Iran's cooperation with the UN nuclear agency and to discuss outstanding issues.

"This trip needs preparations and content and the aims and schedule of this trip should be determined," Eslami underlined.

Grossi has also claimed that the suspension of talks aimed at the revival of the Joint Comprehensive Plan of Action (JCPOA) and Iran's recent measures to reduce its compliance with the 2015 nuclear deal meant that the IAEA could no longer effectively monitor the country's nuclear program. 

He also touched on IAEA's so-called probe into what the agency claims are the presence of "undeclared uranium particles" at some nuclear sites in Iran.

Eslami said the West is waging a psychological warfare operation by accusing Iran of failing to honor its commitments under the JCPOA, while the fact remains that Tehran met all its commitments under the deal.

The official reiterated that Iran is committed to its obligations under the 2015 agreement and as the signatory of the Nuclear Non-Proliferation treaty (NPT), which is evident from numerous inspections of its nuclear facilities by the UN agency inspectors. 

"The agency has carried out around two-thousand inspections [of countries’ nuclear facilities] between 2020 and 2022, and over these three years, five hundred inspections -- that is one-quarter of all inspections -- were conducted in Iran," the nuclear chief underscored. 

"They still feel concerned [about Iran's nuclear work] and this shows their language is the one used by enemies and aimed at a sabotage operation, [but] we won't be affected by them," Eslami stated.

He stressed that the Israeli regime's influence over the UN nuclear agency and hostile moves against Iran over its nuclear work must end. 

Iran has always had full cooperation with the IAEA and allowed it to visit the country’s nuclear sites, but calls the nuclear agency's approach unconstructive and destructive. But Tehran has asked the IAEA to avoid politicizing the issue and focus on technical aspects in line with the organization’s mandate.

Iranian officials have repeatedly called on Director general of the IAEA Rafael Grossi to stop Israeli-influenced approach, and emphasized that Tehran would never surrender to the political behavior of the UN nuclear watchdog that is affected by the Zionist pressures.

They rejected remarks by the IAEA chief over "unexplained traces of uranium" amid efforts to restore the 2015 nuclear deal, and advised the IAEA director general not to raise accusations against Iran based on claims made by the Tel Aviv regime and anti-Tehran groups.

Back in September, AEOI Spokesman Behrouz Kamalvandi stated that Tehran has fully cooperated with the IAEA about three sites in question inside the country, adding that detection of nuclear traces at Iranian sites does not mean Tehran has undeclared nuclear material.

"Iran has been fully cooperative regarding the three alleged sites brought up by the nuclear watchdog and has sent information and answers to the nuclear agency's questions and has also held meetings to resolve the ambiguity," the AEOI spokeperson asserted.

“Since the nuclear agency has accounted for all of Iran’s declared nuclear material and there is no discrepancy, the mere detection of contamination in some sites cannot be taken to mean undeclared nuclear material,” he stressed.
