On 21 November 1975, five delegations in the working group of the Council of Western European Union (WEU) propose a draft reply to Assembly Recommendation 264 on the proliferation of nuclear weapons, adding various details to the version proposed by the French delegation. They are keen to emphasise the fact that the signatory states to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) attach great importance to the improvement of international relations, while bearing in mind that France is the only WEU Member State not to have signed the treaty.
