Non-state actors, such as NGOs, multinational corporations, and international organizations, play pivotal roles in international relations by influencing policy and shaping global governance. They contribute to addressing transnational issues like climate change, human rights, and humanitarian crises, often filling gaps left by states. Their involvement can enhance cooperation among countries and facilitate the exchange of ideas and resources. However, the increasing power of non-state actors also raises questions about accountability and the legitimacy of their influence in global policymaking.
