France reconfirms strong support for the CTBT

The Executive Secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Lassina Zerbo, visited France from 1 to 3 February. In Paris, he met French Foreign Minister Laurent Fabius and other high-ranking officials.


Recalling President François Hollande's speech at the Istres airbase in February 2015, where he described the CTBT’s entry into force as the country’s “first priority” in the field of nuclear disarmament, Fabius and Zerbo discussed ideas to advance the Treaty’s entry into force by seizing the opportunities offered by recent successes of multilateral diplomacy, such as the recently implemented Joint Plan of Action on Iran’s nuclear programme and the climate change conference COP21.

Fabius and Zerbo discussed the 6 January 2016 announced nuclear test by the Democratic People’s Republic of Korea (DPRK) and the need not to disassociate the DPRK issue from the CTBT’s entry into force as it is the sole consensus instrument to stop nuclear explosions.


In this context and on the occasion of the CTBT's 20th anniversary, ‎Zerbo encouraged Fabius to exercise France's leadership and to work with partners for identifying a roadmap with concrete steps to progress towards entry into force. They also addressed the high-level ministerial event planned for June 2016 in Vienna as an ideal venue to bring together all Annex 2 non-ratifying States and engage with them in a discussion.

Setting up a high level forum to engage with other Annex 2 States to progress the CTBT at its 20th anniversary is an ambitious and good idea. The success of the COP21 should be contagious.French Foreign Minister Laurent Fabius


Discussion at the Fondation pour la Recherche Stratégique

At the Paris-based think tank Fondation pour la Recherche Stratégique (FRS) [Foundation for Strategic Research], Zerbo discussed with journalists, civil society representatives and government representatives about the CTBT’s status, its verification system and the risk of “treaty fatigue” if action is not taken soon.

A legally binding and enforceable CTBT is the sole almost universally accepted, non-discriminatory instrument to advance the cause of nuclear non-proliferation and eventual nuclear disarmament. The discussion further addressed the geopolitical circumstances of the eight remaining non-ratifying Annex 2 States, the prospect for their ratification and/or signature and how France, Europe and partners could contribute to raising the CTBT’s profile and to supporting initiatives that will build confidence among those States.

Talks at the Ministry of Defence

At the Ministry of Defence, Zerbo met Admiral Du Ché, Deputy Director General for International Relations and Strategy. Du Ché pledged his continued support in particular to the technical and scientific development of the CTBT verification system, as well as for an invigorated engagement for the Treaty in particular on the occasion of the 20th anniversary.

On the last day of his visit, Zerbo visited the Centre for scientific and technical study of Aquitaine (Centre d’études scientifiques et techniques d’Aquitaine – CESTA) of the CEA where he was welcomed by François Geleznikoff, Director of CEA/DAM. The scientific and technical cooperation between CTBTO and CEA was reviewed at a meting with all CEA/DAM directors.


Beyond provision of scientific and technical expertise to the activities of the organization, this cooperation has been very active on the development of various components of the verification system ranging from infrasound sensors, radionuclide detectors, radioxenon background measurements, performance models, data processing software to the installation and operation of International Monitoring System (IMS) stations and capacity building. Zerbo also visited the Megajoule Laser facility.

Background

France signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on 24 September 1996, the day it opened for signature. It was the first official nuclear weapon State to have ratified the CTBT (together with the UK) on 6 April 1998. It is the only nuclear weapon State to have permanently dismantled its nuclear test sites. With 17 monitoring facilities, France is one of the largest hosting countries of the IMS. France is also one of the largest financial contributors to the organization with a share of 5.7 % of the regular budget. Through the European Union, France has further made voluntary contributions that enable the CTBTO to refine its capability to detect nuclear explosions.
