This book focuses on the so-called 'new bilateralism' phenomenon, a foreign policy development that has widespread across regions since the mid-1990s. Using the case study of EU-Thailand relations, the book shows that the opportunistic foreign policy behavior of the state is particularly observable in the crisis of multilateralism and that the prospects of bilateral engagement, identity formation and rhetorical action urge the drive to bilateralism with a high degree of pragmatism. With references and index.
