This paper examines the politics of South Korea's multicultural discourse and locates its recent development in the context of a broader analytical discussion about multiculturalism. Utilizing the historical experience of the USA, this paper identifies the three orders of multiculturalism. Up until the civil rights movement of the 1950s and 1960s, the USA exhibited the first-order multiculturalism where diverse populations coexisted under discriminatory policies. The post-civil rights era exemplifies the second-order multiculturalism because it not only institutionalized the equality discourse in public spheres, but also provided legal protection against discriminatory practices. Both Korea and the USA, however, share the challenge of achieving the third-order multiculturalism that fosters inter-cultural understanding and addresses the socially embedded inequalities.
