International Organizations in Public International Law

Introduction – International Organizations

International Organizations (IOs) are entities established by treaties or agreements between states to pursue common objectives under international law. They provide a legal and institutional framework for states to cooperate in areas such as peace and security, economic development, human rights, environmental protection, and humanitarian aid.

IOs are subjects of international law, meaning they can enter into treaties, own property, hire personnel, and participate in legal proceedings. They play a vital role in global governance, bridging gaps between state sovereignty and collective action.

Prominent examples include the United Nations (UN), International Monetary Fund (IMF), World Health Organization (WHO), World Trade Organization (WTO), and International Court of Justice (ICJ).
