A Dictionary of International Organizations: UN, WHO, IMF, NATO, EU, and More

A summary of the roles of, and differences between, 9 international organizations that frequently appear in the news but are easy to confuse.

United Nations (UN) β€” International peace and health organizations Β· Founded 1945

International Monetary Fund (IMF) β€” International economic and financial organizations Β· Founded 1944 (Bretton Woods Conference)

An organization that provides funding to member countries facing balance-of-payments crises and monitors exchange rate and financial stability. Its financial support is usually accompanied by policy conditions such as structural reforms.

World Bank β€” International economic and financial organizations Β· Founded 1944 (Bretton Woods Conference)

World Trade Organization (WTO) β€” International economic and financial organizations Β· Founded 1995 (succeeding the GATT system)

North Atlantic Treaty Organization (NATO) β€” Regional cooperation bodies Β· Founded 1949

A military alliance built on a collective defense treaty (Article 5 of the North Atlantic Treaty) that treats an armed attack on any member as an attack on all.

European Union (EU) β€” Regional cooperation bodies Β· Founded 1993 (Maastricht Treaty takes effect)

Rooted in the European Economic Community (EEC), launched by the 1957 Treaty of Rome, it developed into today's EU β€” a political and economic union β€” with the 1993 Maastricht Treaty. It is characterized by a single market and a shared currency (the euro).

Association of Southeast Asian Nations (ASEAN) β€” Regional cooperation bodies Β· Founded 1967

What's the difference between the IMF and the World Bank?

Both were launched together at the 1944 Bretton Woods Conference, but their roles differ. The IMF provides short-term funding to countries experiencing a temporary foreign exchange crisis and monitors exchange rate and financial stability, while the World Bank focuses on providing long-term development funding for infrastructure-building or poverty-reduction projects in developing countries.

What is the relationship between the UN and its specialized agencies?

A significant number of organizations that don't include "UN" in their name, like the WHO or UNESCO, are actually UN "specialized agencies." They operate with their own independent budgets and member-state systems while cooperating with the UN as a whole through the UN Economic and Social Council.
