Kim Jong-un is set to become first North Korean leader to cross into South Korean territory since the end of the Korean War
Kim Jong-un is set to become the first North Korean leader to cross into South Korean territory since the end of the Korean War in 1953, as final details are put in place for the summit.
South Korea said President Moon Jae-in would personally meet Mr Kim at the border at 09:30 (00:30 GMT) on Friday.
The historic talks will focus on the North's recent indications it could be willing to give up its nuclear weapons.
Observers say the summit could provide a breakthrough after years of tension.
Mr Kim is set to cross the military demarcation line - a clearly defined marker of the official land border between the territories. He will, however, remain within the Demilitarised Zone.
Seoul has warned reaching an agreement aimed at ridding Pyongyang of its nuclear weapons will be "difficult", because North Korea's nuclear and missile technology has advanced so much since the sides' leaders last met more than a decade ago.
"The difficult part is at what level the two leaders will be able to reach an agreement regarding willingness to denuclearise," South Korean presidential spokesperson Im Jong-seok said.
The meeting - the third of its kind following summits in 2000 and 2007 - is the result of months of improving relations between the two Koreas, and paves the way for a possible meeting between Mr Kim and US President Donald Trump.
Mr Kim announced last week that he would suspend nuclear tests for the time being. The move was welcomed by the US and South Korea as a positive step, although Chinese researchers have indicated that North Korea's nuclear test site may be unusable after a rock collapse following its last test in September.
As well as addressing Pyongyang's nuclear ambitions, the leaders are expected to discuss a path to peace on the peninsula to formally end the 1950-53 Korean War, and a series of economic and social issues.
South Korea and the US say they are suspending annual military drills for a day while the summit takes place.
