SEOUL (REUTERS) - South Korean President Moon Jae-in and North Korean leader Kim Jong Un will visit Mount Baektu in North Korea on Thursday (Sept 20), a spokesman for South Korea's presidential office said on Wednesday.

North Korea agreed at an inter-Korean summit in Pyongyang on Wednesday to "permanently" abolish its key missile facilities in the presence of foreign experts.

It also said it was willing to close its main nuclear complex if the United States takes unspecified reciprocal action.
