President Moon Jae-in may send a special envoy to Pyongyang, possibly National Intelligence Service (NIS) chief Suh Hoon, as early as next month, sources said Tuesday.

One source, asking not to be named, said this is one option Moon and his aides are considering to find a breakthrough in stalled denuclearization talks between North Korea and the United States.

The special envoy would also discuss the possibility of another summit between Moon and North Korean leader Kim Jong-un, he said.

Seoul is currently looking to end the impasse in nuclear talks between Washington and Pyongyang after the failure of the Hanoi summit last month. It is also trying to keep the momentum of nuclear negotiations alive with Moon taking an active role in facilitating future Trump-Kim meetings.

"The envoy will also discuss advancing inter-Korean ties as well as detailed steps toward dismantling the North's nuclear program such reporting undeclared nuclear sites," another source said.
