Latest developments

Palau was one of the co-sponsors of the 2021 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'.1

At the 2020 UN General Assembly's High-Level Plenary Meeting to Commemorate and Promote the International Day for the Total Elimination of Nuclear Weapons, Palau's President, Tommy E. Remengesau Jr, remarked that the TPNW is '[a] sign of what is possible when we are committed to dialogue, solidarity and peaceful cooperation. This work of fostering new norms for peace and security is one of the strengths of the United Nations. That nuclear possession is as immoral as nuclear use. Palau was one of the first countries to ratify this treaty, and our Constitution enshrines a commitment against the possession of nuclear weapons. [...] We urge all other member states to join us.'2


  • Palau should continue to encourage other states to adhere to the TPNW.
  • Palau should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
