Singapore

Nuclear-weapon-free state

Participated in TPNW negotiations

Has not yet joined TPNW

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

Singapore participated in the negotiation of the treaty at the United Nations in New York in 2017 and was the only state to abstain from voting on its adoption. It said that a number of its suggestions had not been reflected in the final text. 

In a statement to the United Nations in October 2019, Singapore said that the treaty and other instruments relating to nuclear weapons provide “the international community with multiple pathways to a nuclear-weapon-free world”. 

Singapore abstained from voting on 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, Singapore voted in favour of the UN General Assembly resolution that 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”.

Singapore was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.

Singapore is a state party to the 1995 Treaty of Bangkok, which established Southeast Asia as a nuclear-weapon-free zone.
