The current state of global health and foreign policy is being impacted by a shift towards a multipolar world, where multiple countries hold significant power. This shift is leading to a reevaluation of multilateralism and global institutions, with some countries potentially retreating from these institutions. The resulting complex web of crises, referred to as a "polycrisis" or "multi-crisis" world, is being studied and analyzed in terms of its causes and implications for international relations, including the rise of countries like China and the evolution of us-china relations.
