Latest developments

Singapore 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.

The Permanent Mission of Singapore to the United Nations said in February 2021 that there had 'been no changes to Singapore's position' on the TPNW.1

Singapore associated itself with a statement on behalf of ASEAN in the First Committee of the 2021 UN General Assembly, which said that the TPNW 'is a historic agreement which contributes towards nuclear disarmament and complements other existing instruments'.2


  • Singapore should urgently adhere to the TPNW.
