The legal problems brought about by the changes of the international situation and the system construction in the process of domestic independent opening are the two main factors that affected the study of China’s international economic law in 2018. The application and interpretation of the “a Community of Shared Future for Mankind” in the context of the new era，“The Belt and Road” construction and its legislative guarantee，the specific legal issues such as those in the trade disputes between China and the United States and the WTO reform，attracted lots of study and achieved some theory breakthrough. The depth and breadth of academic research in international economic law need to be continuously deepened and innovated according to the requirements of practice. It still needs the unremitting efforts of the international economic law community to continue to maintain sensitivity to the times and promote to the consolidation of the basic theories of international economic law，and achieve balanced development of both branches and mainstream of international economic law.
