Four Decades of India Bangladesh Relations The book Four Decades of India Bangladesh Relations: Historical Imperatives and Future Direction is a joint effort of scholars from the Institute for Defence Studies and Analyses (IDSA), New Delhi and Bangladesh Institute for International and Strategic Studies (BIISS), Dhaka. This book brings out perspectives from India and Bangladesh on various important issues of bilateral cooperation. Bringing together scholars from two premier think tanks in India and Bangladesh who play an important role in providing policy inputs, generating informed debates and discussion and act as an interface between policy makers and the people, this is the first effort of its kind. The book has thirteen chapters on major bilateral issues and nine annexures. The authors have dealt not only with problems but have also suggested various measures to take the bilateral relations forward. Given the nature of the India-Bangladesh relationship, there is a need for greater bilateral engagement at the highest level. A congenial atmosphere would provide an opportunity to heal the relationship that is bound by historic socio-cultural ties. Envisaging a commonality of interests, and delineating the means to achieve this would provide a road map for further enhancement of ties between India and Bangladesh.
