Iran may withdraw from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) if the "snapback" mechanism is enforced during the ongoing nuclear negotiations, a senior Iranian official announced on Tuesday.

Ebrahim Rezaei, spokesman for the Iranian parliament's national security and foreign policy commission, revealed the possibility during a press conference, citing a report by Iran's deputy foreign minister. "If snapback is activated, leaving the NPT is one of our options," Rezaei said, according to the state-run IRNA news agency.

The "snapback" mechanism, part of the 2015 Joint Comprehensive Plan of Action (JCPOA), allows the reimposition of United Nations sanctions lifted under the agreement. The warning comes as tensions rise over Iran’s nuclear program and its cooperation with the international community.

On Friday, Iran held nuclear talks with France, Germany, and the United Kingdom after the UN nuclear watchdog adopted a resolution accusing Tehran of inadequate cooperation. Iran responded to the resolution by announcing it had begun operating more advanced centrifuges, escalating concerns among Western powers.

The talks, attended by Iran’s deputy foreign ministers Majid Takht Ravanchi and Kazem Gharibabadi, were described by Rezaei as an exchange of opinions rather than formal negotiations. “We did not negotiate in Geneva, but simply discussed and exchanged opinions,” Rezaei stated, adding that defining Iran's cooperation framework with Western nations remains a work in progress.

Despite its claims of a peaceful nuclear program, Iran has faced persistent scrutiny from the West. Foreign Minister Abbas Araghchi warned ahead of the talks that if Western nations enforce the snapback sanctions, the debate in Iran could shift toward more drastic measures, including leaving the NPT.

The JCPOA, signed in 2015, offered Iran relief from international sanctions in exchange for restrictions on its nuclear enrichment program. However, the agreement began unraveling in 2018 when the U.S., under President Donald Trump, withdrew from the deal and reimposed harsh sanctions as part of its "maximum pressure" campaign.

Tehran described the Trump administration's attempt to trigger snapback sanctions as an "extreme case of bad faith." Meanwhile, Iran's nuclear activities have expanded, prompting criticism from the U.S., which in February described Iran's cooperation as "severely lacking."

While Iranian officials have pledged continued cooperation with the International Atomic Energy Agency (IAEA), talks with Western powers remain distant from a resolution. The situation underscores the fragile state of international efforts to curb Iran's nuclear ambitions and restore trust between Tehran and global powers.
