Evolving Security Architectures in Southeast Asia: A Study of Regional Security Multilateralism The central theme of this monograph is to analyse the emerging security architecture in Southeast Asia. The evolving internal and external developments which confronts Southeast Asian countries has led to the emergence of a complex regional security environment. The ongoing United States-China rivalry in which Southeast Asia finds itself at the centre, is a key factor in shaping the regional security outlook. The study examines the role of ASEAN in shaping the security architecture centered on its norms and upholding multilateralism. However, the ineffectiveness of ASEAN as an informal security arrangement raises concern over the future of security multilateralism. Further, at a time of weakening multilateralism, along with the emergence of new and renewed security alignments being witnessed in the Indo-Pacific; the ASEAN's centrality comes under increasing pressure. Therefore, an examination into the role of major powers and the new bilateral and mini-lateral security arrangements, provides the future roadmap for security multilateralism in Southeast Asia.
