Talks between Washington and Pyongyang have stalled since the Singapore summit in June, despite positive momentum stemming from a meeting between Kim and South Korean President Moon Jae-in last month.
South Korean Unification Minister Cho Myoung-gyon gave an estimate of between 20 and 60 functional North Korean nuclear bombs to parliament on Monday.
U.S. Secretary of State Mike Pompeo is now scheduled to meet North Korean leader Kim Jong Un on Sunday where the men are expected to negotiate another summit between Trump and Kim.

It's unclear whether they will meet Kim before returning home on Saturday.
"Opportunities to engage diplomatically, if they're actually going to be successful, can be warranted, but if there's no sense of progress I should urge the president not to do the meeting", Gardner said.
It will be the fourth trip by Pompeo to the longtime U.S. pariah amid American hopes of reaching an agreement to end North Korea's nuclear and ballistic missile programs.
"We see this as a consistent effort, before, during and after any diplomatic efforts by the United States and the worldwide community, " said Joyce, describing North Korea as being "undeterred" and urging the USA government to provide more specific threat information to financial institutions about APT38's modus operandi.
Those incidents, including the Cheonan sinking, were not North Korea attacks but rather "accidental armed conflicts", according to the South Korean military, JoongAng Ilbo reported Thursday.
