Power shifts, regionalism, and new rules of global governance

This cluster tracks how intensifying great-power rivalry—especially between the United States and China—is reshaping global governance, trade, security, and markets. It highlights competing visions of world order (U.S. unipolarity vs. Chinese-led multipolarity), the rising role of regional blocs and institutions (from BRICS to Amazon border regions and ASEAN border governance), and new forms of corporate and public diplomacy amid mounting geopolitical risk. Essays and policy pieces examine how regionalism can stabilize global politics, manage issues like health security and migration, and reframe ethical agendas, while case studies on tariffs, nuclear diplomacy, and leadership crises at global forums underscore how institutional rules and legitimacy are being contested. Together, the posts show a world moving from a U.S.-centric system toward a more fragmented, negotiated, and regionally anchored order.
