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.
Bolton told CBS's "Face the Nation" that Washington has devised a program to dismantle North Korea's weapons of mass destruction - chemical, biological and nuclear - and ballistic missile programs in a year, if there is full cooperation and disclosure from Pyongyang.
"If they have the strategic decision already made to do that and they're cooperative, we can move very quickly," he said. "Physically we would be able to dismantle the overwhelming bulk of their programs within a year."
He said Secretary of State Mike Pompeo will likely discuss that proposal with the North Koreans soon. The Financial Times reported that Pompeo was due to visit North Korea this week but the State Department has not confirmed any travel plans.
South Korea media reported on Sunday that Sung Kim, the U.S. ambassador to the Philippines, met with North Korean officials on Sunday at the border village of Panmunjom within the demilitarised zone separating the two Koreas to coordinate an agenda for Pompeo's next visit to North Korea.
Kim's delegation delivered Pompeo's letter to Kim Yong Chol, a top Pyongyang official who met Pompeo and U.S. President Donald Trump ahead of last month's historic summit between Trump and North Korean leader Kim Jong Un in Singapore, Yonhap news agency said, citing an unnamed diplomatic source.
