苏联中央执行委员会
On 17 July 1937, the Central Executive Committee of the Soviet Union issued a resolution declaring all frontiers "special defense zones", and several ethnic minorities in those border areas were considered threats to Soviet security, including Germans, Poles and Koreans. Soviet newspaper "Pravda" accused Koreans of being agents of Japan, while the Soviet government closed the borders and initiated a "frontier zone cleansing".
