The book problematises the evolution, relevance and changing contours of emerging economic and security architectures and connects these to various unilateral and multilateral initiatives that undergird the overall transformation in these economic and strategic multilaterals in this region. The chapters offer a comprehensive overview of organisations and institutions, and the contributors provide their historical background and contemporary focus with implications for the future. Consequently, the book provides a balanced assessment of evolving trends elucidated by both its theoretical debates and empirical analyses. It assesses the outline and influence of non-traditional threats that have received only stand-alone, and not integrated, examination involving issues as climate change, piracy, smuggling and terrorist activity, triggering a whole gamut of humanitarian and disaster relief strategies. Comprehensive in analysis and approach, the book will be of interest to scholars of Political Science, Foreign Policy, Security Studies, International Relations, International Political Economy and Area Studies, including Asian, East Asian or Indo-Pacific Studies.
