Openness and Foreign Policy Reform in Communist States [PDF ebook] 

This book looks at the way in which foreign policy has changed in communist states. It considers especially the relationship between domestic reform and foreign policy reform at times when formerly closed societies are becoming more open to the outside world.It focuses on three European and three Asian states, analysing their different paths to reform and looking in depth at the question of why some communist regimes collapse and why those in Asia have proved more durable than those in Europe.
