Kim Jong Un and Moon Jae-in kicked off the afternoon portion of the summit with a ceremonial tree-planting ceremony in the demilitarized zone.
Kim arrived in the DMZ in his limousine, again with his bodyguards running alongside the vehicle.
After Kim shook hands with Moon, the two shoveled some soil onto a pine tree that was already in the ground before the leaders arrived.
The tree is from 1953, the year the Korean War armistice was signed. Kim used soil from a mountain on the southern island of Jeju while Moon used earth from Mount Paektu in the north.
Each leader watered the tree with water from the other's territory.
After the tree planting, they each revealed a stone that commemorated the occasion, with the phrase "peace and prosperity planted" on it. The leaders' names and the date was also printed on the stone.
