This book conceptualises the ongoing hydropower expansion in Southwest China as a socio-political and transnational project transcending the construction of dams. Chapters in this volume are organised around three sections spanning hydropower and resettlement governance, rural livelihoods, and international relations connected to China’s hydropower expansion. Dam projects of various scales are analysed as infrastructure projects that shape peoples’ livelihoods, the environment, and China’s relations with Southeast Asia, Africa, and Latin America.
