Transnational flows and influx influence perspectives about the concepts of citizenship limited within nation-state borders. The author challenges liberal assimilationist conceptions of citizenship education in order to explore possibilities for the advancement of both multicultural citizenship and global citizenship education. He situates South Korea's case within this discourse and suggests multicultural citizenship and global citizenship education as alternative, defensible, and appropriate paradigms at the transnational and global age. In the final part of the paper, he discusses the implications of this paradigm for citizenship education in South Korea.
