Normative regionalism has been largely overlooked and ignored; and normative questions concerning regionalization are deemed unimportant, idealist and irrelevant to Asia. This is mainly due to the domination of realism, pragmatism and functional approaches, thus inhibiting the substantial progress of regionalism in East Asia. It is time that scholars and policy-makers take normative orders of regionalism seriously. This chapter examines the state of normative regionalism and its impact in East Asia through an overview of the historical evolution of the concept of regionalism, the meanings of and variations in Asian regionalism, and the impact of all these on regional cooperation in East Asia. It examines the old pan-Asianism, the advocacy of "re-Asianization" in Japan, Mahathir's idea of neo-Asianism in Malaysia and the ideas of regionalism developed in Korea and China. This examination provides the basis for a discussion of the normative order of East Asian regionalism by addressing a set of questions concerning national sovereignty, nationalism, democracy and regional identities. In particular, this chapter will examine how Asian nationalist and statist normative thinking influences various ideas of regionalism and constrains the development of genuine regionalism in East Asia.
