By studying the significance and mechanisms of cultural internationalism, this book aims to help emerging international powers constructively engage in global governance in a multipolar world, with particular regard to cultural considerations. Global governance has, to a degree, become more significant than traditional power politics on the international stage. Against this backdrop, the author proposes the idea of a cultural internationalism that centers upon cultural interactions, dialogues and mutual learning, and he calls for international cooperation and a reconstruction of the world order. The rise of the G20 and BRICS countries is cited as an example of the efficacy of international coordination communities built upon both cultural consensus and shared economic foundations, as well as international interactions. The author also delves into China's case to explore practical approaches to the fostering of supranational responsibilities while not neglecting national interest. The book will appeal to academics and general readers interested in international relations, globalization, and Chinese diplomacy.
