Latest developments and background

On 26 September 2019, Samoa’s Prime Minister Tuilaepa Sailele Malielegaoi said in the UN that his country had signed and rapidly ratified the TPNW to underscore its commitment to the NPT goals. He also said that the Treaty's “success over time will depend o the commitment of each and every UN member state. Each new signature and ratification of the treaty ban will strengthen global norms against these weapons of terror and move us closer to a nuclear-weapon-free world. And the only guarantee humankind has against the use and the threat of use of nuclear weapons is through the non-possession and total elimination of all nuclear weapons.” (
