Papua New Guinea

Nuclear-weapon-free state

Participated in TPNW negotiations

Has not yet joined TPNW

Papua New Guinea has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons.

PNG participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

PNG voted in favour of a UN General Assembly resolution in 2018 that welcomed the adoption of the treaty and 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”.

In its opening statement to the negotiating conference, PNG said that the treaty is “inspired by our collective moral and ethical obligations” and that “this conference must pave the way for a new world order”.

PNG submitted a working paper to the conference with detailed suggestions for preambular paragraphs and operative provisions of the treaty.

In 2016, PNG was an additional 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”.

PNG 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.

PNG is a state party to the 1985 Treaty of Rarotonga, which established the South Pacific as a nuclear-weapon-free zone.
