||By the late 1980s, South China, Taiwan and Hong Kong had experienced very rapid economic integration. This new South Chinese Triangle possesses the following distinguished features: state-societal disjuncture, intersitial spatial integration, asymmetrical socio-economic and political status, and contradictory unification forces. After characterizing the South China Triangle, this paper addresses the socio-political consequences of the economic integration in the form of massive investment in Guangdong and Fujian on both Hong Kong and Taiwan. How did economic integration transform state-business relationship, class conflict, identity politics and democratic struggles in Hong Kong and Taiwan? This paper further argues that although Hong Kong and Taiwan have shared a common pattern of economic nexus with South China, the socio-political impacts are quite different. In this respect, the new South China Triangle possesses the dynamics of both the economic centripetal force and the socio-political centrifugal force. Finally, this paper explains how these two forces have shaped and affected Hong Kong and Taiwan's prospects of 'unification' with China since the 1990s.
