Tonga

State with nuclear-free security policy

Tonga voted in favour of adopting the TPNW at the UN Diplomatic Conference in 2017, but has not yet adhered to the Treaty and abstained on the UN General Assembly resolution on the TPNW in 2020. Tonga 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 Pacific Small Island Developing States (PSIDS), Tonga 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 said: 'The world does not need nuclear weapons. The challenges of nuclear disarmament can only be resolved by a strengthened multilateral system that sets the conditions for transparency, confidence-building and co-operation. The NPT, the CTBT and the TPNW are crucial if we are to further the objective of reducing and eliminating nuclear weapons. Today, we PSIDSs say no to nuclear weapons, and we reiterate our commitment to the elimination of nuclear weapons everywhere. We encourage member states to ratify the CTBT and the TPNW. It is morally right, and we owe it to ourselves and our future generations.' See: bit.ly/36QVwUU.

Recommendations

  • Tonga should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty.
  • Tonga should conclude and bring into force an Additional Protocol (AP) with the IAEA. Tonga should also sign and ratify the CTBT.
