The Soviet policy of "korenizatsiya" (indigenisation) resulted in the creation of 105 Korean village soviets (councils) in mixed-nationality "raion", as well as an entire "raion" for the Korean nationality, the Pos'et Korean National Raion; these conducted their activities entirely in the Korean language. The Soviet Koreans had a large number of their own official institutions, including 380 Korean schools, two teachers' colleges, one pedagogical school, three hospitals, a theatre, six journals, and seven newspapers (the largest of which, "Vanguard", had a circulation of 10,000). The 1937 Census showed 168,259 Koreans in the Soviet Union. However, officials in the Russian Far East viewed the Koreans' ethnic and family ties to the Japanese Empire with suspicion, which would soon set the stage for the deportation of the whole population.
