He added Iran and the IAEA had a "longstanding" history of cooperation, which allows for the resolution of remaining differences "provided that external political pressures on the agency are eliminated and the IAEA adopts an independent, technical, impartial, and professional approach."

Gharibabadi stressed that while safeguarding its national security and interests, "Iran remains committed to cooperating with the IAEA within the framework of its safeguards obligations."

Iran signed a nuclear deal, the Joint Comprehensive Plan of Action (JCPOA), with world powers in July 2015, accepting restrictions on its nuclear program in exchange for lifting sanctions.

However, the United States withdrew from the agreement in May 2018 and reinstated sanctions, prompting Iran to scale back some of its nuclear commitments.

Efforts to revive the JCPOA commenced in April 2021 in Vienna. Despite multiple rounds of negotiations, no substantial progress has been reported since talks in August 2022.
