The United States has suspended support for dozens of international organizations following a review of its role in global institutions. The decision affects 66 bodies, many of them linked to the United Nations system, and follows an executive order directing U.S. agencies to end participation and funding.

The move covers a wide range of groups, including agencies involved in climate talks, labour issues, migration and social programs. It also includes U.S. withdrawal from treaties and specialized organizations connected to the United Nations. The White House said the review focused on whether continued involvement matched current U.S. policy priorities.

The decision comes as the United Nations manages a large and complex funding system. The UN system as a whole received about $67.6 billion in total revenue in 2023. That figure includes money flowing to many separate agencies, programs, and operations and can change from year to year.

Most UN funding comes from governments. Around $13.8 billion in 2023 came from assessed contributions, which are mandatory dues paid by member states. About $46.7 billion came from voluntary contributions, which are optional and often tied to specific projects. More than half of that voluntary funding is earmarked for particular uses. The rest of UN revenue, roughly $7 billion, came from sources such as investments and service fees.

The United States has been the single largest contributor to the UN system overall, with other major donors including Norway, Sweden, and China. Funding is split across different parts of the UN, and the headline totals do not reflect the size of its core operating budget.

The UN’s regular budget, which covers central operations such as political missions and human rights work, is much smaller. The approved budget for 2024 is about $3.59 billion. This is separate from peacekeeping budgets, which total more than $6 billion a year, and from the budgets of specialized agencies that operate independently.

By pulling back from selected organizations, the United States reduces both its financial role and its formal involvement in parts of the international system. The changes continue a broader shift in U.S. foreign policy that places less emphasis on multilateral institutions and more on national decision-making.
