North and South Korean officials held high-level negotiations at the border truce village of Panmunjom on Monday to discuss the summit.
The two sides did not announce an exact date for the talks.
The Koreas said in a statement they reviewed ways to set up agreements made at the past summits during nearly two hours of talks on Monday.
The meeting between delegations of senior officials from Seoul and Pyongyang comes as experts see slow progress on efforts to disarm North Korea since a June summit between North Korean leader Kim Jong-un and US President Donald Trump.
Kim has a held a flurry of diplomatic summits with the leaders of South Korea, China, and the United States this year.
South Korean President Moon Jae-in and Kim first met in April in a highly publicised summit and then again in May for more informal talks.
The North has been heavily sanctioned over its pursuit of nuclear weapons and ballistic missiles but Kim and Trump agreed at their landmark summit in Singapore in June to work towards the denuclearisation of the Korean peninsula.
North Korea has denounced US-led efforts to maintain sanctions despite what Pyongyang says are goodwill gestures, including halting its weapons testing and returning the remains of US troops killed in the 1950-1953 Korean War.
