Senior Research Fellow Denise Cheong was invited to participate in the CSCAP Non-proliferation and Disarmament Study Group held virtually on 22 and 23 September 2021. Discussions on recent developments in non-proliferation and disarmament included the outlook for the upcoming Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Conference of the Parties to the Amendment to the Convention on the Physical Protection of Nuclear Material (A/CPPNM). Participants were also introduced to the “Nuclear Responsibilities Toolkit” a toolkit designed to help policy communities think, talk, and write about their nuclear responsibilities, and those of others, in a practical manner.
