neutral zone. In recent years, Chinese fishing vessels have taken advantage of the tense situation in the Han River Estuary Neutral Zone and illegally fished in this area due to both North Korean and South Korean navies never patrolling this area due to the fear of naval battles breaking out. This has led to firefights and sinkings of boats between Chinese fishermen and South Korean Coast Guard. On January 30, 2019, North Korean and South Korean military officials signed a landmark agreement that would open the Han River Estuary to civilian vessels for the first time since the Armistice Agreement in 1953. The agreement was scheduled to take place in April 2019 but the failure of the 2019 Hanoi Summit indefinitely postponed these plans. In 1962, the International Court of Justice had ordered the creation of a "provisional demilitarised zone" around the Preah Vihear Temple whose ownership is claimed by both Cambodia and Thailand. During the Japanese occupation of Manchuria, when they administered as the puppet state of Manchukuo, the Tanggu Truce of May 1933 was concluded between China and Japan, establishing a demilitarised 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 theatre of World War II, Manchuria was re-incorporated into China. Similarly, during the Vietnam War, there was a demilitarised zone between North Vietnam and South Vietnam. The zone was established in July 1954 as a result of the Geneva Conference ending the war between the Viet Minh and France. The DMZ in Vietnam officially lay at the 17th parallel but, in reality, extended about 1.5 km on either side of the Bến Hải River and west to east from the Lao border to the South China Sea. The Vietnamese demilitarised zone was abolished following the reunification of the country in 1976. Europe and the Middle East Demilitarised zones are common in Europe and the Middle East, especially in areas with territorial disputes in the aftermath of military conflicts. Contemporary: The Green Line separating Southern Cyprus and Northern Cyprus is a demilitarised border zone operated by the United Nations Peacekeeping Force in Cyprus The buffer zone was established in 1974 due to ethnic tensions between Greek and Turkish Cypriots.
