First Meeting of States Parties

The first meeting of states parties to the UN Treaty on the Prohibition of Nuclear Weapons will take place at the United Nations Office in Vienna from 22 to 24 March 2022. 

The President-designate of the meeting is Austria's Alexander Kmentt.

At this inaugural meeting, States parties to the TPNW will gather to commit to concrete actions to implement obligations under the Treaty, including on providing assistance to victims of nuclear weapon use and testing, beginning to remediate contaminated environments (Article 6) and universalising the treaty (Article 12). It will also be an opportunity for States to discuss some of the treaty’s technical details, like setting a deadline for the elimination of nuclear weapons for nuclear-armed states that join (Article 4).

Other states not parties to the Treaty, as well as relevant UN agencies, other international organizations or institutions, regional organizations, the International Committee of the Red Cross, the International Federation of Red Cross and Red Crescent Societies and non-governmental organizations, are invited to attend the Meeting as observers.
