This is an unparallelled analysis of the state of the United Nations peace operations and their impact on Asian security.This new volume examines new strategies being adopted by the UN; including doctrinal shifts in peace operation, and assesses the division of labour between the UN, regional organisation and non-governmental organisations/actors. Based on selected papers from mostly Asian scholars, the book offers regional perspectives from South, Southeast and Northeast Asia on the changing nature of UN Peace operations and analyses some of the core issues that are of critical relevance to regional security in Asia. In addition it reveals interesting new insights on the new players in the area of peace operations -- i.e. China and Japan and considers their projected roles as defined by their respective security concepts. It also delves into issues of possible areas of concern caused by the new activism of these regional powers in peace operations. Finally, the book also revisits the significant lessons learnt from the UN experience in Cambodia and East Timor and examines their impact on future directions of peace operations. This book was previously published as a special issue of the leading journal International Peacekeeping.
