The current whirlwind of diplomacy and negotiations will not end with "a honest and complete disarmament" but with "a reduced North Korean nuclear threat", said Thae Yong-ho, who fled his post as the North's deputy ambassador to Britain in August 2016.
KCNA did not report details of the group's activities, but high-ranking officials from Beijing and Pyongyang are believed to have exchanged views on the summit to be held between North Korean leader Kim Jong Un and U.S. President Donald Trump on June 12 in Singapore.
North Korea would then become, a "nuclear power wrapped around paper called 'denuclearization, '" concluded Thae.
While South Korea's presidential office had said that Kim told South Korean President Moon Jae-in during their summit last month that worldwide experts will be invited to witness the closure, the North's Foreign Ministry statement on Saturday did not include any references to allowing experts at the site.
Banks says it remains to be seen whether the talks with Kim Jong Un will produce a deal and what it will involve. "It can never happen", Thae said. And he points to North Korea's turnabout from a year ago, when it launched more nuclear tests than at any point in its history, to pausing the program.
US Secretary of State Mike Pompeo said on Sunday that if the DPRK could achieve denuclearization, "We will have to provide security assurances to be sure", referring to the US commitment to the Pyongyang's regime security.
Thae also noted that North Korea was likely to open its borders to tourism projects near its coast. Abe will also press Trump to bring up the abduction issue during his meeting with Kim.
While the United States wishes that dismantlement be done within months or up to two years, the North wants a longer period of time to carry out denuclearization.
Pompeo said the United States would "work with them to develop infrastructure, all the things that the North Korean people need, the capacity for American agriculture to support North Korea so they can eat meat and have healthy lives". Kim traveled to Beijing in March to hold talks with Chinese President Xi Jinping, and last week the two leaders met again for two days in the northeastern Chinese city of Dalian.
"North Korea's diplomacy has always been a repeat of hardline and appeasement", Thae said.
