This paper provides a broad introduction to the special issue and examines the main contours of regional governance in the Asia Pacific. It suggests that prevailing theories of regional co-operation in the Asia Pacific fail to pay due heed to the manner in which regional integration is rooted in domestic coalitions, economic strategies, and state forms that prevailed in the boom years of the 'Asian Miracle'. The paper then goes on to argue that the collapse of the developmentalist project has given way to the new regulatory state, which in turn spawns new forms of regulatory regionalism that place a heavy accent on policy co-ordination and harmonisation.
