Negotiating the Treaty Prohibiting Nuclear Weapons: Cooperation and Relations Provisions

A three-part series of informal discussions

In this first session, sponsored by the Permanent Mission of Austria, the GCSP and the Geneva Disarmament Platform (GDP) are pleased to invite you to discuss some fundamental concerns surrounding a treaty prohibiting nuclear weapons.

The provisions on cooperation and relations with nuclear-armed states outside the treaty will be of particular relevance for non-nuclear-weapon states that are in military alliances. This session will give the possibility to address some of the key questions: To what extent will the treaty restrict military cooperation with nuclear-armed states? A key goal might be to ensure that states in nuclear alliances are not forced to choose between remaining in the alliance and joining the treaty, but there are different ways of approaching this. In which way could the precedents of the Anti-Personnel Mine Ban Convention and the Convention on Cluster Munitions, serve as basis to addressing the issue under the future treaty prohibiting nuclear weapons? Would a prohibition to assist, encourage or induce include reliance on the nuclear weapons of others? How would this be formulated? What are the options? How far can respective allowances be extended before the normative effect of the treaty begins to suffer? Might there be value in formulating prohibitions or restrictions broadly (e.g. a general prohibition on “assistance” with acquisition, deployment or use of nuclear weapons)?

The format for the meeting will be as follows:

  1. Welcome by the sponsoring state
  2. Introduction to the topic by invited experts
  3. Open discussion moderated by the GCSP and the GDP

A light lunch will be provided before the discussion, and a non-attributed summary will be circulated after the meeting. Participants will need to take care of their own access to the Palais.

Participants do not need to register, but they are encouraged to circulate draft working papers, textual proposals, or any other written contribution to the meetings. Papers for circulation, as well as any queries or suggestions, can be sent to Richard Lennane and Marc Finaud


This series of discussions will take place before the negotiations on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination” which will begin in New York on 27 March, following the adoption of General Assembly resolution 71/258.
