South Korea's Unification Minister Ryoo Kihl-Jae, speaking on a television talk show today, quoted Kim Yang-Gon as saying: "There is nothing wrong with the health of Secretary Kim".
Kim Yang-Gon, who heads a ruling party department in charge of South Korea-related affairs, visited the South's western port of Incheon yesterday to attend the closing ceremony of the Asian Games, along with two other high-ranking officials.
The minister said Hwang had asked him to deliver a "heartfelt greeting" from Kim Jong-Un to South Korean President Park Geun-Hye, but there was no specific message from the leader.
The North's leader has not been seen in public for a month, fuelling rumours about his health and even triggering reports of a coup.

A rare admission from North Korea nine days ago that he was suffering "discomfort" triggered frenzied speculation and close scrutiny of any mention of the young leader in state media.
The rumours multiplied after he failed to attend a meeting of the North's rubber-stamp parliament last week.
Kim, believed to be 30 or 31, took over the reins of power in North Korea following the death of his father Kim Jong-Il in December 2011.
