CTBTO Must Credibly Confirm Dismantling & Closure of DPRK Nuclear-Weapon Test Site

By Tariq Rauf *

While North Korea has invited journalists from a handful of countries to witness the dismantling and closure of its nuclear-weapon test site at Punggye Ri, only the Vienna-based Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has the required expertise, verification technology and credibility to confirm the closure of the Punggye Ri test site.

Contrary to popular belief, the highly competent International Atomic Energy Agency (IAEA) has expertise only in monitoring and verification of civilian nuclear programmes, but not in the areas of dismantling of nuclear weapons and dismantling of nuclear-weapon test sites.

The IAEA monitors the “upstream” dimension of nuclear weapons development while the CTBT is intended to monitor the “downstream” final proof of a State's intention to develop nuclear weapons – that is, the actual nuclear test explosion.

UN and CTBTO Hail End to Nuclear Testing by North Korea, Denuclearization Remains a Mirage

By Ramesh Jaura

BERLIN | VIENNA (IDN) – UN Secretary-General António Guterres and Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) Executive Secretary Lassina Zerbo have welcomed the announcement by the Democratic People's Republic of Korea (DPRK) to halt its nuclear testing programme and to dismantle the test site.

The announcement came six days ahead of the DPRK leader Kim Jong-un's meeting with President Moon Jae-in of the Republic of Korea (South Korea/ROK) taking place on April 27. After the inter-Korean summit, Kim is expected to meet with U.S. President Donald Trump in June 2018.

U.S. Undermining the Global Nuclear Testing Taboo

By Ramesh Jaura

BERLIN | GENEVA (IDN) – A new document that outlines U.S. nuclear policy, strategy, capabilities and force posture for the next five to ten years proclaims that the Trump Administration does not intend to ratify a global treaty banning nuclear weapons tests. Nor does it rule out resuming such tests.

The document, titled 2018 Nuclear Posture Review (NPR), proclaims that "the United States does not support the ratification of the CTBT." But the U.S. will continue to support the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO).

Action Needed to Ratify the 1996 Nuclear Test Ban Treaty

By Dr Lassina Zerbo

The author is Executive Secretary of CTBTO, Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization. The following is a slightly abridged and modified text of his address on 26 February to the High-level segment of the Conference on Disarmament, multilateral disarmament negotiating forum where the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in Geneva was negotiated in the 1990s. (Read the original text here.) Dr. Zerbo stressed that "we must take great care to preserve the integrity of the institutions and instruments we have and to build trust in them and around them. This means maintain and securing the NPT and its entire chain of responsibilities – of which the CTBT entry into force is an integral part". – The Editor
