Global power structures refer to the distribution of power and influence among countries and international organizations. These structures shape global politics, economics, and security, often determining how resources and responsibilities are shared. Key players include major nations like the United States, China, and Russia, as well as organizations such as the United Nations and the World Trade Organization. These power dynamics can lead to cooperation or conflict, influencing global issues like trade, climate change, and human rights. Emerging powers and regional alliances also play a role, challenging traditional hierarchies and creating a more multipolar world where influence is increasingly shared among various actors.
