The 20 Years CTBT Ministerial Meeting brought together leaders and policymakers to discuss, review, and reinvigorate the discussion on the CTBT. By providing a venue for participants to voice their needs, security concerns, and demands, the Ministerial Meeting stimulated the discussion needed on the issues currently blocking the entry into force of the worldwide ban on nuclear explosions.

This year represents an opportune moment to engage in these discussions. Marking 20 years after the Treaty opened for signature, the eight remaining Annex 2 countries that have still to ratify the Treaty were invited to join Member States and the CTBTO to discuss what is required to turn the global moratorium on nuclear testing from de facto into de jure.

Other events held on the sidelines of the Ministerial Meeting included a civil society panel entitled “[email protected]: The Way Forward - The role of Civil Society” and the opening of the [email protected] exhibition.

The High Level Ministerial Meeting started on 13 June 2016, at the Vienna International Centre, Vienna, Austria - see first day summary.
