India is known as a leading voice in international affairs. India's economic size, vast and growing market, democratic institutions, access to ocean and foundation of science largely explain why India continues to play an important role in global and regional affairs. India is the only country in Asia having the heft to counterbalance China and thus welcomed by many countries in Asia and the Pacific. India has embarked on a period of radical changes in its foreign and economic policies. Faced with a major slowdown of India's trade with Southeast and East Asia in 2014-15, the government responded by initiating far-reaching Act East Policy (AEP) aimed at greater eco-nomic integration with South, Southeast and East Asian nations. Started with a fresh vigour in 2014, AEP has gained a new momentum while acting on the east. The Act 'East' is now getting transformed into Act 'Indo-Pacific'. This book presents short essays written by the author on several key aspects of India's economic relations and the challenges faced by India in the post-AEP period. Ten broad themes are analysed in this book: BBIN, BIMSTEC, SAARC, ASEAN, MGC, Act East–North East, BCIM, BRI, Act Far East and Indo-Pacific. This volume highlights what, in au-thor's best judgement, should be the direction for India's expanding neighbourhood. It is an economist's insight and field experience based analysis that offers guidelines for international cooperation. This volume is an invaluable companion for the policymakers, academia, students of international relations, diplomats and the general readership as well.
