We cannot expect in East Asia over the foreseeable future to see the sort of conflation of sovereign states that has occurred in Europe. We must anticipate that, for the foreseeable future, the requirement will be for the sensible management and containment of competitive instincts. The establishment of a multilateral security body in East Asia that includes all the key players, and which the major powers invest with the authority to tackle the shaping of the regional security order, remains a critical piece of unfinished business.

This book is based on the proceedings of the National Security Seminar 2011 conducted at the USI from 17 to 18 Nov 2011. The views of eminent speakers from across the globe have been covered on the following themes:- • Strategic and Security Environment in the Asia Pacific Region • Existing Political and Economic Frameworks in the Asia Pacific: Have they fulfilled regional aspirations? • Bringing an Enduring Security Architecture for the Asia Pacific This book intends to examine the current state and possible future trajectory of efforts to create an Asia Pacific security architecture. The problems are challenging but not insurmountable. Efforts to build an appropriate security architecture would certainly be in the interest of the region.

The security architecture of the Asia/Pacific region is in a profound transformation. Such changes are not without problems, which are discussed here.

The topic of this book deals with a highly relevant empirical issue: East asian security and the dynamics of the respective governance structure or architecture are not only of regional but of global concern. Since the pivot of the American pivot to East Asia and other external actor ́s responses to it the security architecture has changed in form, size and function. In order to analyze and explain these changes, hypotheses derived from IR middle range theories (i.e. soft and hard balancing) will be applied to cases of bilateral and multilateral security governance in East Asia.

In the turbulent decade since the ending of the Cold War in Europe, a new element of the international relations of Asia and the Pacific has been the emergence of multilateral security dialogues. Both in governmental arenas such as the ASEAN Regional Forum and numerous "track two" channels including the Council for Security Co-operation in Asia-Pacific, it has been a decade of creative interaction and new thinking. The Asia-Pacific Security Lexicon identifies the key phrases and ideas that have been the foundation of these dialogues, looking at their origins in international diplomacy and tracing their specific adaptation and modification to the conditions of a trans-Pacific setting. Of interest to both theoreticians and practitioners, the Lexicon is at once a handbook for regional diplomacy and an assessment of the factors that have shaped regional discussions.
