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.
