 Passage 3:Koryo-saram is the name which ethnic Koreans in the Post-Soviet states use to refer to themselves. Approximately 500,000 ethnic Koreans reside in the former USSR, primarily in the newly independent states of Central Asia. There are also large Korean communities in southern Russia (around Volgograd), the Caucasus, and southern Ukraine. These communities can be traced back to the Koreans who were living in the Russian Far East during the late 19th century. There is also a separate ethnic Korean community on the island of Sakhalin, typically referred to as Sakhalin Koreans. Some may identify as Koryo-saram, but many do not. Unlike the communities on the Russian mainland, which consist mostly of immigrants from the late 19th and early 20th centuries, the ancestors of the Sakhalin Koreans came as immigrants from Gyeongsang and Jeolla provinces in the late 1930s and early 1940s, forced into service by the Japanese government to work in coal mines in order to fill labour shortages caused by World War II.
