The government announced earlier that Kim Yong-chol, a vice chairman of the Central Committee of North Korea's ruling Workers' Party, will make a three-day visit to South Korea as the head of an eight-member high-level delegation to the closing ceremony of the PyeongChang Winter Olympics.
Kim, a former top military official who headed North Korea's reconnaissance bureau, is suspected of having orchestrated Pyongyang's two deadly attacks on the western coast in 2010 -- the sinking of the Cheonan warship and the shelling of Yeonpyeong Island.
Forty-six sailors were killed in the Cheonan's sinking and two marines and two civilians were killed in the island shelling.
The South has accepted the North's offer and President Moon Jae-in will meet with the delegation, officials said.
The main opposition LKP strongly protested the planned visit.
More details with Korean political commentator Jung-sik Seo are available in audio news.
