South Sudan

South Sudan acceded to the Biological Weapons Convention (BWC) in April 2023. South Sudan abstained from voting on the annual UN General Assembly resolution on the TPNW in 2023, having voted in favour of it in 2021 and having been absent for the vote in 2022. 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.

Latest developments

In January 2023, South Sudan participated in an African regional seminar on universalisation of the TPNW in Pretoria, hosted by the South African foreign ministry.1

The Ministry of Foreign Affairs said in February 2020 that South Sudan supports the TPNW and the goal of abolishing nuclear weapons and intends to become a state party 'in due course'.2

Recommendations

  • South Sudan should urgently adhere to the TPNW.

  • South Sudan should adhere to the Pelindaba NWFZ Treaty.

  • 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 Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Comprehensive Nuclear-Test-Ban Treaty (CTBT), and the Chemical Weapons Convention (CWC).
