Leszek Buszynski 
Gorbachev and Southeast Asia (Routledge Revivals) [PDF ebook] 

First published in 1992, this book examines Soviet foreign policy towards Southeast Asia in the context of the transformation of the perestroĭka era in the Soviet Union. The discussion begins in 1985 and ends in 1989 with the Soviet partial withdrawal from Cam Ranh Bay. Buszynski considers Gorbachev’s effort to disengage from the Cambodian problem, the weakening of the Soviet alliance with Vietnam and the real effort to overcome old hostilities with growth areas in ASEAN such as Thailand and Singapore. This is a fascinating and relevant title, of particular value to students with an interest in Russia and the history of international relations in Southeast Asia.
