This book aims to provide an analysis of Cambodia-Thailand diplomatic relations over the past seven decades, specifically from 1950 to 2020. While other academic publications have focused on particular aspects of Cambodian-Thai relations (e.g. border conflicts or cultural ties), this book is the first to cover a comprehensive history of diplomatic relations between the two countries starting from the establishment of official diplomatic ties in 1950 to the present.

As such, it is postulated that Cambodia-Thailand diplomatic relations should not be seen simply as relations between two unitary states cooperating with or securitizing against one another, but rather as a matrix of intertwining relationships between various social and political groups in both states harboring competing ideologies and/or interests to advance their power positions at home.
