National culture is a collection of material and spiritual civilizations formed by a nation's diverse production and living activities, and it reflects the historical characteristics of a nation. Under the influence of “the Belt and Road Initiative (B&R)”, expanding the influence of China's excellent traditional culture is an important task to pioneer in the new era. Based on the outline of this initiative, the global promotion of China's unique traditional culture essentially entails the mutual integration of Chinese civilization and other countries' civilizations, the inheritance and the dissemination of Chinese cultural genes. A fundamental principle of the B&R is the promotion of win-win cooperation among countries along the silk road. Through this new international cooperation platform, China has given new impetus to common development and promoted mutual understanding, respect and trust among countries. The construction of a discourse system embodies not only a theoretical construction but also the inheritance and forging of a powerful force that influences human behavior. This paper discusses the connotation of China's excellent traditional culture and the problems of traditional cultural communication from the perspective of the "B&R" and analyzes the integration and innovation path of the "B&R" traditional cultural discourse system.
