Statement by Lassina Zerbo, Executive Secretary, Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO)

Vienna, 21 April 2018


I welcome the announcement by the Democratic People's Republic of Korea (DPRK) to halt its nuclear testing programme and to dismantle the test site. This is a strong signal and an important step in the right direction.

As a next step, the DPRK, along with the other remaining Annex 2 countries, should consider signing and ratifying the Comprehensive Nuclear-Test-Ban Treaty (CTBT)  to solidify this progress. A legally binding in force CTBT is the only way to solidify the moratorium on nuclear testing and an essential step towards the ultimate goal: a world free from nuclear weapons.

The CTBTO stands ready to assist in whatever way we can.

Background

The CTBT bans all nuclear explosions. The Treaty will enter into force once signed and ratified by the remaining eight nuclear technology holder countries: China, Egypt, the DPRK, India, Iran, Israel, Pakistan, and the United States.

A verification regime is being built to monitor compliance with the Treaty. Nearly 90 percent of the 337 facilities of the International Monitoring System (IMS) are already in place. The system swiftly, reliably and precisely detected all six DPRK declared nuclear tests. After the DPRK announced nuclear test on 12 February 2013, the CTBTO was the only organization to detect radioactivity attributable to the event.
