Has ratified the TPNW
Nauru has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.
Marlene Moses, the permanent representative of Nauru to the United Nations, signed the treaty on 22 November 2019.
The instrument of ratification was deposited on 23 October 2020.
Nauru participated in the negotiation of the treaty at the United Nations in New York in 2017 but was absent for the vote on its adoption.
In 2016, Nauru was a co-sponsor of the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.
Nauru was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.
Nauru, together with Fiji, Palau, Samoa, and Tuvalu, submitted a working paper to a UN working group in Geneva in 2016 in which they argued that “the debate should no longer be about whether a global ban on nuclear weapons is necessary, but rather how we can achieve it and what provisions it should contain”.
The five Pacific island states commented that the lived experience of nuclear weapons in the Pacific, where more than 300 atomic and hydrogen bombs were tested, has motivated them to work for a treaty-based ban.
Nauru is a state party to the 1985 Treaty of Rarotonga, which established the South Pacific as a nuclear-weapon-free zone.
