"In parallel with dismantlement of the nuclear test ground, guards and researchers will be withdrawn and the surrounding area of the test ground will be completely closed", the ministry said.
The official Korean Central New Agency said dismantlement of the Punggye-ri nuclear test ground would involve collapsing all of its tunnels with explosions, blocking its entrances, and removing all observation facilities, research buildings and security posts.
"It would, however, require North Korea to clear out the test tunnels and rebuild any infrastructure that might be removed - or dig new tunnels at the site or elsewhere". It is already believed to be unusable after Pyongyang's...
Amid concerns that North Korea will demand America withdraw its troops from neighbouring South Korea, Kang emphasised that the US military presence there must be "a matter for the US-South Korea "alliance first and foremost".
