This book offers a groundbreaking exploration of area studies, marking the first comprehensive volume in China addressing both theoretical and empirical dimensions of this field. Edited by Professor Zhang Yunling and translated into English by Professor Wang Liqin, the book compiles contributions from distinguished scholars across various Chinese universities and research institutions. Published initially in Chinese in 2022, it aligns with the Ministry of Education's 2021 initiative to pioneer area studies in China, ushering in a 'golden age' for this discipline. This volume provides an interdisciplinary framework essential for understanding the complexities of international regions. It systematically defines key concepts, explores research methodologies, and distinguishes between region-based and nation-based studies. The book delves into themes of politics, economy, culture, and governance, tracking the emergence, growth, and disappearance of international regions, and analyzing their interconnectedness and governance. With a rich array of extended readings, it serves as a vital resource for students and scholars of area studies, international relations, and political science. As the first volume of the 'Study of International Regions' series, it sets the stage for future works on regional governance and identity, aiming to enhance global academic dialogue and understanding of China's latest research in area studies.
