Book excerpt: The South Asian security complex refers to security interdependencies between the states in the region, and also includes the effect that powerful external actors, such as China, the US and Russia, and geopolitical interests have on regional dynamics. This book focuses on the national securities of a number of South Asian countries in order to discuss a range of issues related to South Asian security. The book makes a distinction between traditional and non-traditional security. While state-centric approaches such as bilateral relations between India and Pakistan are considered to be traditional realist approaches to security, the promotion of economic, environmental and human security reflect global concerns, liberal theories and cosmopolitan values. The book goes beyond traditional security issues to reflect the changing security agenda in South Asia in the twenty-first century, and is a useful contribution to studies on South Asian Politics and Security Studies.
