Tonga

Nuclear-weapon-free state

Has not yet joined the TPNW

Summary

Tonga has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons.

 

National position

Tonga abstained from voting on an annual UN General Assembly resolution in 2020 that welcomes the adoption of the treaty and calls upon all states to sign, ratify, or accede to it “at the earliest possible date”.

 

Treaty negotiations

Tonga participated in the negotiation of the treaty at the United Nations in New York in 2017 and was among 122 states that voted in favour of its adoption.

In 2016, Tonga voted in favour of the UN General Assembly resolution that established the formal mandate for states to commence negotiations on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

 

Before the negotiations

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. Tonga supported calls in the UN General Assembly fill this “legal gap”.
