Seoul, Dec 21 (TIWN) North Korean leader Kim Jong-un might announce the suspension of nuclear talks with the US when he delivers his New Year's Day address or holds a key meeting of the ruling Workers' Party later this month, an expert said.

Sung Ki-young, a senior researcher at the Institute for National Security Strategy made the remarks during a North Korea forum on Friday amid heightened concerns Kim could put his threat to take a "new way" into action, reports Yonhap News Agency.  The North Korea leader gave the US until the end of this year to come up with a new negotiating proposal satisfying Pyongyang's demands, strongly suggesting that otherwise, he could restart tests of nuclear weapons or intercontinental ballistic missiles (ICBMs).
