North Korea insists its leader Kim Jong-un has "no problems" with his health, South Korea's unification minister said Sunday, one day after a rare visit by North Korean high-ranking officials to the South.
Unification Minister Ryoo Kihl-jae made the remarks after he met a delegation headed by Hwang Pyong-so, believed to be the second-most powerful man in the communist regime, on Saturday in the western port city of Incheon.
