Point of view
"There's a lot of preparations that go into these kinds of meetings so we'll have to consult our American partners and to make sure that if it takes place it's a meaningful meeting with good outcome."South Korean Foreign Minister
Halting Pyongyang's nuclear weapons programme is a key condition for any future summit with US President Donald Trump.
Kang Kyung-wha told CBS that Kim had "given his word", adding that it was "the first time that the words came directly" from him.
The report comes as North Korea's Foreign Minister arrived in Beijing after three days of talks with his Swedish counterpart.
Sweden has been touted as a possible venue for a Trump-Kim meeting. Pyongyang hasn't publicly confirmed any plans.
