DMZ (Demilitarized zone)
A demilitarized zone, DMZ or DZ is an area in which treaties or agreements between nations, military powers or contending groups forbid military installations, activities or personnel. A DMZ often lies along an established frontier or boundary between two or more military powers or alliances. A DMZ may sometimes form a de facto international border, such as the 38th parallel between North and South Korea. Other examples of demilitarized zones are a 120-mile (190 km) wide area between Iraq and Kuwait, Antarctica (preserved for scientific exploration and study) and outer space (space more than 100 miles (160 km) from the earth’s surface).
Many demilitarized zones are considered neutral territory because neither side is allowed to control it, even for non-combat administration. Some zones remain demilitarized after an agreement has awarded control to a state which (under the DMZ terms) had originally ceded its right to maintain military forces in the disputed territory. It is also possible for powers to agree on the demilitarization of a zone without formally settling their respective territorial claims, enabling the dispute to be resolved by peaceful means such as diplomatic dialogue or an international court.
Several demilitarized zones have also unintentionally become wildlife preserves because their land is unsafe for construction or less exposed to human disturbances (including hunting). Examples include the Korean Demilitarized Zone, the Vietnamese Demilitarized Zone, and the Green Line in Cyprus.
Korean Demilitarized Zone
The Korean Demilitarised Zone (DMZ; Chosŏn’gŭl/Hangul: 한반도 비무장 지대; Hanja: 韓半島非武裝地帶) is a strip of land running across the Korean Peninsula. It is established by the provisions of the Korean Armistice Agreement to serve as a buffer zone between North Korea and South Korea. The demilitarized zone (DMZ) is a border barrier that divides the Korean Peninsula roughly in half. It was created by agreement between North Korea, China and the United Nations in 1953. The DMZ is 250 kilometres (160 miles) long, and about 4 kilometres (2.5 miles) wide.
Within the DMZ is a meeting point between the two nations in the small Joint Security Area (JSA) near the western end of the zone, where negotiations take place. There have been various incidents in and around the DMZ, with military and civilian casualties on both sides.
