The current status and challenges of china railway express (Cre) as a key sustainability policy component of the belt and road initiative

Under the auspices of the Belt and Road Initiative (BRI), China has been expanding the operation of its CRE (China Railway Express) system that links China and Europe. The CRE is today regarded as an important measure of progress by which BRI-related goals are achieved, and it has the potential to become the most sustainable mode of long-range transport. The system has been growing rapidly thanks to the active support of the Chinese government. As the Eurasian trade and logistics environment changes, CRE will become increasingly important as a third option that complements air and sea transport, with the demand continuing to accelerate among shippers for CRE service. Despite the expanding role and potential importance of the CRE system, few academic studies have been undertaken on the relevant CRE policies and status, especially in international academic journals. Thus, this study comprehensively reviewed the specific operation status of CRE system by route and region, and identified specific challenges that need to be addressed in order to continue its sustainable development.
