States with nuclear-free security strategies

Singapore participated in the TPNW negotiations, but was the only state to abstain on the vote when the Treaty was adopted. Singapore has not adhered to the TPNW, but maintains policies and practices that are compliant with all of the prohibitions in Article 1 of the Treaty and can therefore sign and ratify it without making changes to existing practices or policies.

Latest developments and background

Singapore is categorized by the Ban Monitor as "undecided" on the TPNW. In First Committee of the UN General Assembly in 2018, the representative of Singapore said his country is committed to the goal of a nuclear-weapon-free world, the only guarantee against their use. Singapore regretted that concerns it has about the TPNW were not taken into account when the instrument was negotiated. "While there are multiple pathways towards a nuclear-weapon-free world, all parties must be involved in the process," he said, adding that Singapore will continue to work constructively toward that goal.
