Latest developments

South Sudan participated in the TPNW negotiations in 2017, but did not cast a vote on the adoption of the Treaty. In 2021, it voted in favour of the annual UN General Assembly resolution on the TPNW for the first time. In previous years, it had not cast a vote.

South Sudan maintains policies and practices that are compatible with all of the prohibitions in Article 1 of the TPNW, and can therefore sign and ratify or accede to the Treaty without the need for a change in conduct.


  • South Sudan should urgently adhere to the TPNW.
  • South Sudan should conclude and bring into force a Comprehensive Safeguards Agreement and an Additional Protocol with the IAEA. South Sudan should also adhere to the NPT, the CTBT, the BWC, and the CWC.
