States Parties


Nauru participated in the Second Meeting of States Parties to the TPNW (2MSP) in November and December 2023, where it reaffirmed its ‘unwavering dedication to the collective pursuit of a world free of nuclear weapons’. It noted the long history of support for nuclear disarmament in the Pacific, ‘borne of our region’s direct experience of nuclear testing by colonial powers, the catastrophic humanitarian and environmental consequences of which still reverberate today, serving as a reminder of the urgency of our collective task’.[1]

Latest developments

At the 2MSP, Nauru welcomed the important work being undertaken to implement the TPNW’s provisions on victim assistance and environmental remediation ‘for people and places harmed by nuclear weapons use and testing’. ‘These efforts are integral to the TPNW’s humanitarian response to nuclear weapons,’ it said. It warned that nuclear weapons ‘continue to pose threats to global peace and security, our environment, our existence. … We recognise and support the important role that the TPNW plays in achieving its overarching goal, which is to work towards the total elimination of nuclear weapons.’ It also urged all states to ratify the Treaty ‘so we are united in the global vision for a peaceful and just world, free of nuclear weapons’.2

Nauru was one of the co-sponsors for the 2023 UN General Assembly resolution on the TPNW, which 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’.3


  • Nauru should continue to encourage other states to adhere to the TPNW.

  • Nauru should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.

  • Nauru should bring into force its Additional Protocol with the IAEA.
