Racial nationalism is an ideology that advocates a racial definition of national identity. Racial nationalism seeks to preserve "racial purity" of a nation through policies such as banning race mixing and the immigration of other races. To create a justification for such policies, racial nationalism often promotes eugenics, and advocates political and legislative solutions based on eugenic and other racial theories.
Nationalism in Northeast Asia (China, Korea and Japan) is partly related to 'racial nationalism' (民族主義), it was influenced by the German ethnonationalist tradition (Völkisch movement and Blood and soil) of the 19th century, which was imported from Japan during the Meiji period. This kind of nationalism is related to the term 民族 similar to the German word Volk.
