One of the incidents that took place in Korean literature in the 2000s was the influx of aliens. Literary critics have paid a huge attention to the influx of others who are different from Korean people in appearance and language and are called foreigners or immigrants. There are tremendous theoretical and practical discussions on the influx of Others in the fields of criticism and discourse, and the discourses are based on the theories of most influential theorists. It implies that it`s required to deliberate on national border and to change the way of looking at the influx of Others, and that literature should first assume the responsibility for that. The purpose of this study was to examine Korean novels in the area of Korean literature in an effort to look into discussions about multiculturalism. This evolves into a political science of approval that refers to equally valuing every culture that exists in the world, or is manifested in the form of a liberalistic cultural theory that argues every cultural community must guarantee the right of individuals to choose and decide. Against the arguments of multiculturalism, there is a criticism that respecting cultural diversity is just following the strategies of multinational companies or that it could merely be reduced to an effective means of labor control. In this context, the so-called identity politics that basically advocates approval of different cultural contexts and respect for difference will be bound to admit its own limitations.
