Regionalism, membership and leadership: insights from Asia and beyond

Abstract

Drawing inspiration from a Chinese proberb, this paper offers an alternative interpretation of regionalism, with a special reference to its membership. This alternative interpretation provides insights into the exclusionary aspect of regionalism, for which mainstream international relations theories lack a certain efficacy in providing plausible explanations. We hypothesize that a state forms a regional group in which it can be a leader, excluding states that are more powerful than it is. A state values the leading position in a regional group, even in a small regional group. To test the hypothesis, this paper investigates regionalism launched in Asia during the second half of 20th century, with special attention to the inclusion and exclusion of the US. By analyzing diplomatic records obtained at four national archives (Australia, Japan, the UK, and the US), as well as memoirs by retired officials and other studies, this paper shows that regionalism in Asia was often pursued in an exclusionary manner, mainly by Japan, and to a lesser degree by Indonesia. The paper also discusses whether and how regionalism in Europe can be explained with this alternative theory.
