New problems and challenges in international economic law in the context of the Coronavirus Outbreak and trade frictions between major countries and China’s response are the themes of China’s international economic law research in 2020. The impact of the global new crown pneumonia epidemic has brought new challenges to WTO reform and the reform of the international investment dispute settlement mechanism. China and the United States signed the Economic and Trade Agreement between the Government of the People’s Republic of China and the Government of the United States of America as the first phase of the agreement，pressing the “pause button” for Sino-US trade friction. The concept of “Community with a Shared Future for Mankind” and the Belt and Road initiative have demonstrated their advantages in the impact of the global new crown pneumonia epidemic on international economic and trade rules. The adoption of the “Measures for the Security Review of Foreign Investment” shows that while my country remains open in the international economic and trade system，it also pays attention to preventing and dissolving national security risks，and escorting a higher level of opening up. In 2020，international economic law has concentrated research on the above aspects and achieved certain results. The international economic and trade rules system will always be in a process of equilibrium and rebalance. How to deeply grasp the trend of international economic and trade rules and make theoretical contributions to my country’s response still requires unremitting efforts from the international economic law circles.
