Im Jong-seok, President Moon Jae-in's chief of staff and head of a summit preparation committee, told a briefing on Monday that the delegation will include about 50 members of the press as well as South Korean government protocol, security and administrative support staff, and some senior lawmakers.

The South Korean government recommends National Assembly Speaker Moon Hee-sang and chairmen of major parties, both ruling and opposition, to accompany President Moon Jae-in to attend the summit. The meeting will be the third this year between Moon and Kim, following ones in April and May, both of which were held in the Panmunjeom border village in the Demilitarized Zone dividing the Koreas.
