President Moon Jae-in is expressing hope the leaders of the U.S. and North Korea will make bold decisions at Tuesday's summit in Singapore, to open a new era of peace on the Korean Peninsula.

In a meeting of his top aides on Monday, Moon said that he has every confidence the summit will be a success, after seeing both leaders demonstrate their strong will to resolve North Korea's nuclear issue.

At the same time, he stressed that deep-rooted hostility cannot be resolved in a single action, but will be a long process that may take years.

He said South Korea should not rely only on North Korea-U.S. dialogue, but should focus at the same time on developing inter-Korean relations.
