@ Saniya:
I would suggest you to go through the following writings:
1- Globalization of World Politics by Steve Smith and John Baylis (preferably 5th edition, or, at least, 4th edition;
2- World Politics: Trends and Transformation by Charles Kegley Jr.;
3- Pakistan's Foreign Policy by S.M. Burke-- Pak-US relations, Pak-USSR relations, Pak-India relations, and Pak-China relations;
4- Pakistan and Geostrategic Environment by Hassan Askari Rizvi (McMillan Press)-- For the above topics and having a cursory glance on the contours of major powers' foreign policies;
5- American Foreign Policy by Bruce W. Jentleson (For having a deep grasp on US foreign policy); and
6- China in World Politics: Policies, Processes, Prospects by Judith F. Kornberg, John R. Faust (For having a deep grasp on China's Foreign Policy).
The aforementioned is a complete and comprehensive package for having complete grip on the subject.
I have all the above-mentioned writings. Therefore, if you do not get your hands on the books, you can ask without any hesitation.
