Latest developments

Solomon Islands 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.

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, Solomon Islands associated itself with a statement by the Pacific Small Island Developing States (PSIDS), 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.'1


  • Solomon Islands should urgently adhere to the TPNW.
  • Solomon Islands should conclude and bring into force an Additional Protocol with the IAEA, and upgrade to a Modified Small Quantities Protocol. Solomon Islands should also ratify the CTBT.
