This book presents a comprehensive analysis of China&s evolving security engagement in Africa, a dimension often overshadowed by earlier studies focusing on economic and political aspects. As China&s global ambitions expand, its involvement in African security-across bilateral, regional, and multilateral levels has intensified, challenging its longstanding principle of non-interference. The book explores why China is shifting from a policy of non-interference to one of ‘non-indifference& and details the actions supporting this change. Employing neoclassical realist theory, it examines systemic factors, domestic influences, and the role of President Xi Jinping in shaping China&s security strategy. By adopting a three-dimensional approach to Sino-Africa relations and categorizing the reasons for China&s policy shift into strategic culture, superpower ambitions, operational motives, and reputational concerns, the book offers fresh insights into China&s security diplomacy. It contributes to the broader discourse on China&s changing stance and its implications for international relations, highlighting the need for attention in both academic and policy circles.
