CRRC is the largest rail transit manufacturing enterprise in the world. It is also China’s “golden card” in the international market，and a model for the international development of China’s infrastructure industry. This section takes CRRC as the research object，expounds its internationalization development process and current situation，analyzes the motivation of internationalization of CRRC and the key factors of its internationalization success，and provides some suggestions for enterprises to go abroad under the “The Belt and Road” initiative. Research believes that the slowed down of the domestic economic growth，the shrunken market，and the opened up policies，the excellent technological innovation and domestic status have pushed CRRC to expand its overseas market and deepen its international development. Meanwhile，the national level initiative，the leading technical advantages of CRRC，the emphasis on cultural integration and the fulfillment of social responsibility also pave a smooth international path for CRRC. Its positive response to national policy initiatives，continuous implementation of innovation strategy，promoting overseas cultural integration and actively fulfilling overseas social responsibility are worthy of reference for domestic enterprises.
