The roundtable conference featured participants from a wide array of stakeholders: representatives of several national missions in Vienna, high-level international and national organizations officials, as well as NGO experts and media. Panelists and participants alike engaged in constructive discussion and lively debate on CTBT-related issues.

The conference consisted of three parts. The first session focused on the role of CTBT in stemming nuclear proliferation and promotion of nuclear disarmament as well as its future contribution to these objectives. Speakers particularly emphasized the normative and moral authority CTBT has developed in the international community and especially the strengthening of a norm — not legally binding, but nonetheless exceptionally strong — that makes nuclear testing an unacceptable behavior.

The second session looked into technical aspects of the international verification system (IMS) and paid particular attention to the enhancement of its capability, in the past 15 years, to monitor compliance with the treaty.

The third, forward-looking part of the conference addressed the prospects of entry of the CTBT into force. Having noted recent ratifications by Indonesia and Guatemala, participants concentrated on discussion of ways to facilitate ratification by the remaining Annex II states. Participants discussed institutional, political, and ideological barriers on that path as well as a range of practical and symbolic measures that could accelerate CTBT's entry into force and strengthen the regime in the meantime.
