Beijing: South Korean President Moon Jae-in says there will be no easing of sanctions against North Korea, despite preparations now under way for North Korea's participation in the 2018 Winter Olympics.

South Korea on Wednesday sent its nuclear envoy to Washington to brief the United States on the high-level dialogue held with North Korea a day earlier.

Tuesday's marathon 11-hour dialogue went beyond Olympic participation discussion, and resulted in North and South Korea agreeing to hold military talks to ease border tensions, and facilitate exchanges in a broad range of areas. A reopened military hotline was tested on Wednesday.

Moon gave credit to the United States for the inter-Korean talks, after a two-year freeze in communication.
