Book excerpt: Unresolved Border, Land and Maritime Disputes in Southeast Asia, edited by Alfred Gerstl and Mária Strašáková, sheds light on various unresolved and lingering territorial disputes in Southeast Asia and their reflection in current inter-state relations in the region. The authors, academics from Europe and East Asia, particularly address the territorial disputes in the South China Sea and those between Vietnam and Cambodia and Thailand and Cambodia. They apply International Relations theories in a wider regional and comparative perspective. The empirical analyses are embedded in a concise theoretical discussion of the principles of sovereignty, territorial integrity and borders. Furthermore, the book discusses the role of the Association of Southeast Asian Nations (ASEAN) and other multi-track mechanisms in border conflict mediation. Contributors are: Petra Andělová, Alica Kizeková, Filip Kraus, Josef Falko Loher, Padraig Lysaght, Jörg Thiele, Richard Turcsányi, Truong-Minh Vu and Zdeněk Kříž.
