WASHINGTON — South Korea’s foreign minister says North Korea’s leader has “given his word” he’s committed to denuclearization, a prime condition for a potential summit with President Donald Trump in May.

Trump has agreed to what would be historic talks after South Korean officials relayed that Kim Jong Un was committed to ridding the Korean Peninsula of nuclear weapons and was willing to halt nuclear and missile tests.

North Korea hasn’t publicly confirmed the summit plans, and a meeting place isn’t known.

South Korea’s Kang Kyung-WHA says Seoul has asked the North “to indicate in clear terms the commitment to denuclearization” and she says Kim’s “conveyed that commitment.”

She tells CBS’ “Face the Nation” that “he’s given his word” and it’s “the first time that the words came directly” from the North’s leader.
