Nuclear-weapon free state
Participated in TPNW negotiations
Has not yet joined TPNW
The Solomon Islands has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons.
The Solomon Islands participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.
The Solomon Islands voted in favour of a UN General Assembly resolution in 2019 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.
In 2016, the Solomon Islands voted in the first committee of the UN General Assembly in favour of a draft resolution that ultimately established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.
Prior to the adoption of the treaty in 2017, nuclear weapons were the only weapons of mass destruction not subject to a comprehensive, globally applicable treaty prohibition. The Solomon Islands supported calls in the UN General Assembly fill this “legal gap”.
The Solomon Islands is a state party to the 1985 Treaty of Rarotonga, which established the South Pacific as a nuclear-weapon-free zone.
