US, Partners Reaffirm UN Restrictions on Iran One Year After Snapback

Shibbir Ahmed, Washington DC  — The United States and dozens of partner countries have reaffirmed their commitment to implementing United Nations restrictions on Iran, one year after a series of UN Security Council resolutions were restored through the so-called “snapback” mechanism. In a joint statement issued October 2, the countries participating in the Proliferation Security Initiative (PSI) said they would continue implementing the obligations contained in six UN Security Council resolutions that returned into force on September 27, 2025.

The resolutions are UNSCR 1696 (2006), 1737 (2006), 1747 (2007), 1803 (2008), 1835 (2008) and 1929 (2010). According to the statement, France, Germany and the United Kingdom initiated the snapback process in response to what they described as Iran’s “persistent and significant non-performance” of its nuclear commitments under the Joint Comprehensive Plan of Action (JCPOA).

The United States and its PSI partners said they remain committed to preventing the supply, sale or transfer to Iran of materials, equipment, goods and technology that could contribute to proliferation-sensitive nuclear activities or the development of nuclear-weapons delivery systems. They also reaffirmed restrictions on the supply, sale or transfer of arms and related materiel to or from Iran.

The participating countries said they would strengthen their domestic legal authorities and capabilities to address proliferation-sensitive activities involving Iran. Their commitments include preventing direct or indirect transfers of items that could contribute to weapons of mass destruction and their means of delivery, including unmanned aerial vehicles (UAVs), as well as materials covered by the reinstated UN arms restrictions.

The countries also pledged to improve information-sharing among PSI partners concerning Iran’s proliferation activities and to review national legal authorities where necessary to ensure that enforcement measures remain effective. They further committed to taking appropriate actions in support of interdiction efforts involving Iran’s proliferation-related activities. The joint statement welcomed national-level efforts to implement the reinstated UN obligations and cited activities linked to Operation Economic Outcast as supporting the broader objective of preventing Iran from acquiring a nuclear weapon.

The participating states called on all UN member countries to implement the reinstated resolutions and said they would continue coordinating counterproliferation efforts to prevent Iran from undertaking activities prohibited under the resolutions, including efforts related to its nuclear and ballistic missile programs. They also urged Tehran to return to compliance with its nonproliferation obligations, cooperate fully with the International Atomic Energy Agency (IAEA), and address what the signatories described as international concerns over Iran’s nuclear activities.

The snapback process began in August 2025, when France, Germany and the United Kingdom notified the UN Security Council that they considered Iran to be in significant non-performance of its JCPOA commitments. The process culminated on September 27, 2025, when the six earlier Security Council resolutions returned into force.

The status and legality of the snapback have been disputed by Iran, which has argued that the mechanism was invalid and that the states invoking it lacked the authority to restore the earlier resolutions. The dispute has remained part of the broader international debate over the future of the JCPOA and Iran’s nuclear program. The October 2 statement was signed by a broad group of PSI-endorsing countries, including the United States, Canada, France, Germany, the United Kingdom, Japan, Australia, Israel, South Korea and numerous European and other partner states.
