Korean Demilitarized Zone The Korean Demilitarized 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.

The only country with a land border to South Korea is North Korea, lying to the north with 238 kilometres (148 mi) of border running along the Korean Demilitarized Zone. South Korea is mostly surrounded by water and has 2,413 kilometres (1,499 mi) of coast line along three seas; to the west is the Yellow Sea (known in Korea as West Sea), to the south is the East China Sea, and to the east is the Sea of Japan (known in Korea as East Sea). Geographically, South Korea's land mass is approximately 100,032 square kilometres (38,623 sq mi).[1] 290 square kilometres (110 sq mi) of South Korea are occupied by water.
