It's by far the most sustained public presence for Kim, who had been something of a mystery to many South Koreans, despite her known role in North Korea's politburo.

"Moon should be aware that he has to urge denuclearisation to North Korea by himself, not depending on dialogue between the US and North Korea", an editorial in the Yomiuri Newspaper read.
