Security is a wide concept, pertaining not only to national security but also to the essential factors of human wellbeing and progress. In the current global climate, many new dimensions to security have become evident through interconnected issues such as climate change, food insecurity, pandemics, and terrorism, making the study of security more relevant than ever. The Asia-Pacific region is confronted with many complex and daunting challenges, including the denuclearisation of North Korea, tensions in the Taiwan Strait, and assertions of sovereignty in the South China Sea. Besides these, recent developments in Afghanistan, emerging trends in transnational terror networks, sectarian violence, drug trafficking and illegal migration are deeper issues that have sustained security concerns in the region. This book studies security issues in the Asian context, recognising the region as a locus of international affairs and power-politics in which security is mostly influenced by geopolitical factors.
