Direct communication needed between leaders of N.Korea, US, South Korea says

Direct communication between the leaders of North Korea and the United States is necessary, South Korea urged on Friday.

The comment followed a letter by U.S. President Donald Trump on Thursday informing North Korean leader Kim Jong Un of his withdrawal from what would have been the two countries' first ever summit, set for June 12 in Singapore.

At a meeting on Friday, security advisers to South Korean leader Moon Jae-in vowed to keep up efforts to improve ties between the two Koreas, which would contribute to better ties between Pyongyang and Washington and complete denuclearisation of the Korean peninsula, a presidential press secretary told a news briefing.
