"The country is a corporation with a government that can exercise a permanent population, clear territory, and sovereignty" (Kegly Jr & Witt Kopf, 2001). International relations can be regarded as studying the role of national and non-state actors in international political systems. This system consists of non-state actors such as sovereign states, states and national states, as well as multinational corporations, intergovernmental organizations, international non-governmental organizations and non-governmental organizations.
International relations theorist James Rosenau uses theoretical dynamics of global governance as a way to simulate international systems. The theory of global governance is paying attention to the growing importance of global civil society. Global governance is "an analytical concept (Meyer) that expands it based on neo-liberal theory before international systems and globalization". Global governance is often seen as managing and solving global issues in political places where there is no single centralized authority. It is "Gordenker and Weiss" to bring more reliable and orderly response to social and political problems that the country exceeds its ability to solve alone. These definitions indicate that global governance includes interdependence between decision making and principals seeking to manage or generate more orderly responses to common problems.
