This book covers the theoretical and historical background of the Belt and Road Initiative （BRI）， its legal， security and environmental preconditions as well as economic， financial and social motivations， and China's interaction with the world economy， etc. It reviews what China has achieved in its reform and opening up and the progress it has made in implementing the BRI with partner countries/regions， and looks into the future of the BRI.Looking back on the past 40-plus years， we see clearly the crucial importance of the reform and opening up policy for China. While advancing its own development， China has always held high the banner of peace， development， cooperation and win-win results， worked to align the Chinese Dream with the global dream， promoted global economic growth through international cooperation platforms such as the Belt and Road Initiative， and provided Chinese proposals for world peace and human development. In this book， Chinese and foreign scholars interpret China's reform and opening up and the Belt and Road Initiative from various perspectives. Their new cross-cultural approach allows readers to better understand China in the context of greater cultural diversity and modernities.
