South Korean President Moon Jae-in on Sunday tapped his national security chief as a special envoy to lead a delegation on a one-day trip to North Korea on Wednesday as Moon seeks to kick-start stalled nuclear negotiations with the U.S. and plan for his third summit with North leader Kim Jong Un later this month.

National security adviser Chung Eui-yong will head the five-member delegation to Pyongyang. The delegation includes spy chief Suh Hoon, Vice Unification Minister Chun Hae-sung, Yun Kun-young, presidential secretary for state affairs, and top NIS official Kim Sang-gyun.

The team consists of the same members that visited Pyongyang for a breakthrough meeting with Kim in early March.
