In the beginning, the Cambodian conflict was a domestic one. But, it soon became international problem after, in 1978, vietnam took a military invasion, set up a pro-Vietnam took a military Penh, and stationed around 200,000 Vietnamese military troops in Cambodia. The Vietnamese military invasion made the Cambodian conflict become more complicated and implicated to other international communities and implicated to other international communities, particularly the neighboring countries, auch as Indonesia and Thailand. Although, like other ASEAN countries, both Indonesia and Thailand wanted the Cambodian conflict to be resolved peacefully, they differed in some ways how the political settlement had to be taken. The main aim of the book is to portrait the Cambodian conflict with all international implications, particularly how the negotiation process for resolving the conflict took place, involving the ASEAN countries such as Indonesia and Thailand, and other international communities.
