The essays in this volume provide the Indian and Southeast Asian perspectives on some of the geo-political and security challenges facing South and Southeast Asia. These include the interests and role of major outside powers in the two regions and the relations between these powers; the trends in Asian regionalism, especially the ASEAN-led regionalism and India's place in it; the growing maritime and naval interests of the two rising Asian powers, China and India; and the impact of climate change. Also addressed are two specific issues of great potential importance for the security calculus of the two regions: the South China Sea and Myanmar.
