Abstract
After the outbreak of COVID-19, such global and public health events have a potential impact on the structure of international relations.Such impacts cover many areas of international relations, such as the stagnation of international economic development, the challenges of international security, and the obvious differences in the level of global health and epidemic prevention.When a real "post-epidemic era" is approaching, we need to conduct effective research and judgment on the international changes in the "post-epidemic era", which has both theoretical academic value and practical needs.The academic community should strengthen in-depth research on the changes in the international situation of peace and development in the "post-epidemic era".Combined with the new world changes, this article attempts to analyze the changes in international relations brought about by the "post-epidemic era" and the challenges faced by maintaining world peace from multiple perspectives.
