The global fight against the coronavirus is still full of uncertain- ties. The world order after World War II proved unfit for the new changes in international politics, economic growth and demands from the international community. Nowadays, multi-polarization is in the ascendancy, economic globalization is imbalanced and global governance leadership is largely absent. New global issues and challenges emerge endlessly, making the current world order increasingly unstable and unpredictable. Establishing a world order that will adapt to the changes in international situations, improve global governance and cooperate in non-traditional security fields such as global health is a key global issue. To discuss these issues, the Center for International Security and Strategy at Tsinghua University organized an international seminar, inviting politicians, scholars, diplomats and policymakers to share their views on the post-pandemic world order and the prospects for international relations.
