The summit will be the third high-level meeting where the two leaders can talk face-to-face, after they first met in Panmunjom on April 27.
ROK's official Yonhap News Agency reported Thursday that the prime topics would be focusing on how to accomplish complete denuclearization and build a peace regime on the Korean Peninsula, citing the country's Vice Unification Minister Chun Hae-sung.
In addition, Chun said that Seoul would "actively implement its summit agreements" with its neighbor, noting his belief that progress made for inter-Korean relations will improve the denuclearization process of the peninsula, according to Yonhap.
Days ago, the two sides agreed on meeting earlier to sort out details for the third Kim-Moon summit. However, the DPRK side has been silent since the beginning of this week.
The autumn summit was decided when Kim and Moon first met back in April. They then met again in May, having organized an impromptu summit after US President Donald Trump pulled out of his then pending summit with Kim Jong Un.
Washington and Seoul have been frustrated that no progress has yet been made on denuclearization, while Pyongyang has complained that despite a weapons test freeze and handover of US military remains, there has been no sanctions relief or a peace agreement to formally end the Korean War.
