A demilitarized zone (DMZ or DZ)[1] is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a Template:Convert wide area between Iraq and Kuwait; Antarctica (preserved for scientific exploration and study); and outer space (space more than Template:Convert from the Earth's surface).
Some zones remain demilitarized after an agreement has awarded control to a state which (under the DZ 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.
Antarctica – The Antarctic Treaty forbids military activity in Antarctica, such as "the establishment of military bases and fortifications, the carrying out of military manoeuvres, as well as the testing of any type of weapon". The Treaty does however provide for the "use of military personnel or equipment for scientific research or for any other peaceful purpose".[2]
Joint Control Commission – Known locally as the Dniester Valley Security Zone, the demilitarized buffer zone was created by the cease-fire agreement ending the War of Transnistria. The Commission's peacekeeping mission monitors the demilitarized zone which roughly outlines the Dnister river between Moldova and Transnistria. It is 225 kilometers long and from 1 to 15 kilometers wide.
Martín García Island – An Argentine island surrounded by Uruguayan waters of the Río de la Plata, according to the 45th article of the Río de la Plata Treaty it states that "the Martín García Island will be destined exclusively as a natural reserve for the conservation and preservation of the native fauna and flora, under the jurisdiction of the Argentine Republic", stating a demilitarized zone in the island.
A neutral territory was established between the British Overseas Territory of Gibraltar and Spain after the end of the 1727 siege. A strip of land 600 toises (about Template:Convert) long,Script error: No such module "Unsubst". more than two cannon shots' distance between the British and Spanish guns, was called "the neutral ground" and shown as such on older maps. In 1908, the British built a fence in a portion claimed to be the British half of the neutral territory. Spain does not recognize British sovereignty over the isthmus (including the border), asserting it is Spanish soil. Although both the United Kingdom and Spain used to be part of the European Union (before the United Kingdom's exit), the border was a de facto international frontier with customs and immigration checks; Spain does not formally recognize it as a "frontier", referring to it as a "fence". Whatever its name, Gibraltar opted out of the European Union Customs Union and is not part of the Schengen Area; the border is open 24 hours a day, with customs duties payable on designated goods entering Spain or Gibraltar.
Israel and Syria: Following the 1948 Arab-Israeli War, three DMZs were created by the 1949 Armistice Agreements between Israel and Syria.[14]
China – The Imperial Japanese Army conquered Manchuria between September 1931 and February 1932, when they proclaimed the region the state of Manchukuo. In May 1933, the Tanggu Truce between China and Japan was concluded, establishing a demilitarized zone between Manchukuo and China. In 1937 Japan violated this truce with an invasion of the remainder of China. In 1945, after the fall of the Japanese empire at the end of the Asia-Pacific theater of World War II, Manchuria was re-incorporated into China.
Ecuador – a demilitarized zone was established on 2 October 1941, after the war between Ecuador and Peru, which existed under Ecuadorian administration and under the observation of neutral mediator nations: the United States, Brazil and Argentina.[15] The DMZ was abolished in 1942, with the withdrawal of Peruvian forces from El Oro Province after the signing of the Rio Protocol.
Norway and Sweden established a demilitarized zone of 1 km (1,100 yards) on each side of their border after the dissolution of the union between Norway and Sweden in 1905. The zone was abolished by mutual agreement in 1993.
