The response to the first three volumes released two and a half years ago was so impressive that it has been decided to release this fourth Volume. This Volume has been brought out at a time when the bilateral relations between India and Pakistan are improving fast. The Volume includes articles by the experts from both India and Pakistan on the subject as well as important documents. The Volume also includes some documents relating to the period before the publication of three volumes because these were not available at that time. It is hoped that the book would be found useful by the students and research scholars of India and Pakistan concerned with international relations. The Volume would also be useful to the parliamentarians and executives of India and Pakistan concerned with the formulation and execution of foreign policy of their respective country. Even the common readers interested in Indo-Pak Relations would find the volumes useful, informative and interesting.
