Iran Iran


States with nuclear-free security strategies

Iran voted in favour of adopting the TPNW at the UN Diplomatic Conference on 7 July 2017. Iran has not yet adhered to the TPNW, but maintains policies and practices that are compliant with all of the prohibitions in Article 1 of the Treaty, and can therefore sign and ratify it without making changes to existing practices or policies.

Latest developments and background

Iran voted yes on the UN General Assembly resolution on the TPNW in 2018. According to Iran, the adoption of the TPNW was a “step forward” in the direction of confronting “bullying policies” ( Iran has recently restarted uranium enrichment (albeit not to a level sufficient for use in a nuclear explosive device) and has threatened to no longer comply with its obligations under the 2015 Joint Comprehensive Plan of Action. The United States had previously withdrawn its support for the agreement and re-imposed economic sanctions on Iran.


  • Iran should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty.
