Renminbi (RMB) internationalization and the "One Belt One Road" initiative are two important development strategies launched by China. From the perspectives of theoretical exploration, historical experience, and empirical research, this book discusses how the two strategies interact with each other. To start with, it introduces the current situation of RMB internationalization and the history of the Silk Road. Then it examines the mutual benefit relationship between the two strategies, emphasizing that commodity pricing and account settlement, infrastructure finance, industry development zone construction, and cross-border e-commerce should be the key to RMB internationalization.
