In Washington, White House spokeswoman Sarah Sanders said in a statement that Moon briefed Trump on his plan to send a special envoy to Pyongyang on Wednesday to meet Kim. They are (from L) Yun Kun-young, a Cheong Wa Dae official, special envoy Chung Eui-yong, Kim, Suh Hoon, head of the National Intelligence Service, Vice Unification Minister Chun Hae-sung and Kim Sang-gyun, a senior NIS official.
"The delegation will set off for North Korea on the fifth via the direct route on the western side of the Peninsula, and they'll return to the South the same day".
A South Korean presidential spokesman said a briefing will be held on the visit on Thursday.
The spokesman didn't say whether the team will be meeting with North Korean leader Kim Jong-un.

The five-member delegation led by Mr Moon's national security adviser arrived in Pyongyang on Wednesday to arrange a third summit between Mr Moon and Mr Kim planned for later this month, to help rescue faltering nuclear diplomacy between Washington and Pyongyang.
North Korea's obsession with an end-of-war declaration may also indicate that it seeks to turn the talks with the United States into an arms reduction negotiation between two nuclear states, rather than a process to surrender its nukes. Washington and Pyongyang have been unable to agree on a timeline for North Korea's promise to denuclearize since Kim met U.S. President Donald Trump in June.
Last month Trump ordered Secretary of State Mike Pompeo to abruptly cancel a planned trip to Pyongyang, citing lack of progress on denuclearisation. Washington is unlikely to provide sanctions relief, diplomatic recognition or the reduction of US forces in South Korea unless North Korea takes major steps on denuclearization.
He described the declaration as a move to realize the political intent for establishing permanent peace on the Korean Peninsula.
