According to the Munhwa Ilbo daily newspaper, the US authorities have detected up to 3,000 nuclear-related facilities in North Korea, which could mean that the inspection of the sites and US-North Korean talks on denuclearization will take considerable time.

On June 12, US President Donald Trump and North Korean leader Kim Jong-un met in Singapore where they issued an agreement that requires Pyongyang to denuclearize in exchange for a freeze on the US-South Korean military drills and eventually sanctions relief.
Earlier this year, the North Korean leader said he was ready to denuclearize and signed a corresponding agreement with South Korean President Moon Jae-in at the inter-Korean summit in the truce village of Panmunjom in April. In May, North Korea, in a gesture of goodwill, blew up three test mines at the Punggye-ri nuclear site, as well as destroyed security checkpoints and other facilities.
