Economic ties between South and East Asia have been growing steadily since the 1990s, fuelled by domestic reforms and emergence of regional production networks. More recently, bilateral and region-level initiatives have also contributed to increasing integration. If such initiatives succeed, could these sub regions grow to become dominant players in global trade? This book evaluates the economic implications of increasing cooperation between the two sub regions, providing empirical analyses for informed policy decisions and improved outcomes. Exploring the role of market forces as well as domestic and regional policies, it examines how integration helps in spurring inclusive economic development, especially in small economies. It also discusses the prospects for India’s integration with East Asia as it looks to increase its engagement with the global economy through greater links with the sub region.
