Ever since China-Europe Rail Express opened to the public， it has developed rapidly and become the most productive trade corridor and a new international logistics public goods of “the Belt and Road” international economic and trade cooperation. However， rapid development has also brought about problems and conflicts， for instance， problems of “scattered， disorderly， and low efficiency” train operation is prominent； “excessive short supply” of transportation resources and “inefficient and wasteful use” of transportation resources coexist； comprehensive transportation costs is comparatively high； subsidies from local governments is huge； bottlenecks exist to varying degree in countries along the belt and road in terms of their infrastructure and service capacity； multilateral cooperation and coordination mechanism needs to be improved and policy support needs to be strengthened urgently； informatization and digitization of the train operation are lagging behind. With China embarking on a new journey of comprehensively building a socialist modernized country and the continuous evolution of worldwide changes of a scale unseen in a century， the high-quality development of China-Europe Rail Express is facing new opportunities and challenges. To achieve high-quality development of China-Europe Rail Express and promote the construction of “the Belt and Road” international economic cooperation and trade corridors， the following policy recommendations are put forward. First， strengthen strategic and overall planning to provide guidance for high-quality development of the Express； Second， cultivate and promote rail hubs with those distribution centers as the core and promote the optimization of train routes so as to achieve a transformation from “point to point” to “hub to hub” operation mode； Third， accelerate pace to improve the policy system for supporting train services， that is， shifting from supplementing freight rates to reducing costs， addressing shortcomings， and improving service levels， and help improve capacities； Four， further improve rail infrastructure along domestic and international routes and enhance the modernization of train services； Five， strengthen cooperation with overseas market players to further gathering international sources of goods and promote the two-way and coordinated development of the Express； Six， improve the level of digital development； Seven， accelerate the improvement of multi-level coordination mechanisms and promote win-win cooperation among the Belt and Road countries.
