Iranian President Masoud Pezeshkian warned on Wednesday that renewed sanctions would eliminate any prospect for dialogue on Tehran's nuclear file.

"The Iranian president stated that if sanctions are reinstated, dialogue will be pointless," Pezeshkian said during talks with Norwegian Prime Minister Jonas Gahr Støre, according to a statement released by the presidential office in Tehran.

The warning comes as discussions about the potential reactivation of the UN "snapback mechanism," which would restore penalties lifted under the 2015 nuclear agreement, resurface in Western capitals. The mechanism is set to automatically trigger this weekend unless a breakthrough is reached in ongoing talks between Iran and the E3, namely France, Britain, and Germany, on the sidelines of the UN General Assembly.

Pezeshkian also held his first bilateral meeting at this year's UNGA with French President Emmanuel Macron. The presidential office said the leaders reviewed Iran's cooperation with the International Atomic Energy Agency (IAEA) and exchanged views on the sanctions issue. Earlier this month, Iranian Foreign Minister Abbas Araghchi and IAEA Director General Rafael Grossi signed a cooperation agreement in Cairo, but Tehran has warned it would be invalidated if sanctions are reimposed.

Meanwhile, Grossi confirmed that IAEA inspectors are on standby to head to Iran should a last-minute understanding be reached. "Everything is possible. Where there is a will, there is a way," he told reporters at the UN, noting that the timing of inspections depends on Iran’s political will.

At home, Sayyed Ali Khamenei reiterated that Iran does not seek nuclear weapons but will not abandon uranium enrichment, which he described as a national achievement with vital civilian uses across agriculture, industry, and energy. He rejected talks with the United States outright, arguing that past experience had shown them to be harmful, while calling on Iran to strengthen itself in the face of Western pressure.

The meetings in New York underline both Iran's continued engagement with European powers and its red line: negotiations cannot proceed under the threat of renewed sanctions, nor at the cost of abandoning enrichment technology that Tehran insists is peaceful.
