The Washington Post reported yesterday that North Korea was considering ways to hide its nuclear weapons and secret production facilities. "Only the Opposition Party, which includes the Fake News, is complaining".
Sung Kim is a former US envoy for North Korea and led policy negotiations with Pyongyang in advance of the summit.
Reports over the past few days indicate that intelligence agencies do not believe Kim Jong-un intends to fully dispose of his nuclear stockpile, and is planning to hide the size of that stockpile and the extent of nuclear facilities while attempting to extract concessions in nuclear talks.
White House national security adviser John Bolton said on Sunday he believed the bulk of North Korea's weapons programmes could be dismantled within a year, as the United States and North Korea resumed working-level talks.
This also comes ahead of U.S. Secretary of State Mike Pompeo's scheduled visit to Pyongyang later this week.
Evidence newly obtained by USA officials points to preparations to deceive the United States about the number of nuclear warheads in North Korea's arsenal as well as the existence of undisclosed facilities used to make fissile material for nuclear bombs, officials told The Post.
Bolton also said the administration's plan would require the North Koreans to provide full disclosure of all their nuclear programs and ballistic missile sites, but that has not happened yet.
However, a North Korean research website called 38 North says satellite images show that the headquarters and other building remain in place.
After promising as a candidate that he would be happy to talk to the North Korean dictator and would "absolutely" try to talk some sense into Kim Jong-un, President Trump began his outreach to him with a series of insulting tweets.
But Pentagon spokesperson Col. Rob Manning told reporters Monday he was unaware of a timeline for any transfer, saying US diplomats are still working with North Korea.
According to reports in South Korea, Sung Kim met with North Korea's Vice Foreign Minister Choi Sun Hee at Panmunjom for an hour and a half Sunday. "I think they want to do it", he said in an interview that aired Sunday.
".And as far as the one-year timeline, Ambassador Bolton said if North Korea makes the decision to denuclearize, their ballistics programs could be dismantled in a year".
Siegfried Hecker, a nuclear scientist and Stanford University professor, has predicted it would take around 10 years to dismantle and clean up a substantial part of North Korea's Yongbyon nuclear site.
