South Sudan

State with nuclear-free security policy

South Sudan participated in the TPNW negotiations in 2017, but did not cast a vote on the adoption of the Treaty and has not adhered to it. The government has also not cast a vote on any of the UN General Assembly resolutions on the TPNW in 2018, 2019, or 2020. South Sudan 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

As a member of the African Group in the UN, South Sudan aligned itself with the group's statement at the 2020 UN General Assembly's High-Level Plenary Meeting to Commemorate and Promote the International Day for the Total Elimination of Nuclear Weapons, which welcomed the adoption of the TPNW and stated that the Treaty does not undermine the NPT but complements and strengthens it. The African Group also called on all states, especially nuclear-armed and umbrella states, to sign and ratify the TPNW, and to consider the catastrophic humanitarian, environmental, and economic impacts of nuclear weapons and to dismantle and renounce these weapons of mass destruction.

Recommendations

  • South Sudan should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty.
  • South Sudan should conclude and bring into force a Comprehensive Safeguards Agreement (CSA) and an Additional Protocol (AP) with the IAEA. South Sudan should also adhere to the NPT, the CTBT, the BWC, and the CWC.
