Answer:
Demilitarized zone
Step-by-step explanation:
The line separating the two Koreas is called the Demilitarized Zone. It was established during the Korean Armistice Agreement, which established a truce in the Korean War and created this zone that serves as a buffer zone and a border, which divides the Korean Peninsula in half, leaving South Korea on one side and North Korea on the other. This region draws a lot of attention from tourists, who can take a guided tour for a fee.
