The United States is the single largest financial contributor to United Nations (U.N.) peacekeeping activities. Congress authorizes and appropriates U.S. contributions, and it has an ongoing interest in ensuring such funding is used as efficiently and effectively as possible.
The United States, as a permanent member of the U.N. Security Council, plays a key role in establishing, renewing, and funding U.N. peacekeeping operations. For 2024, the United Nations assessed the U.S. share of U.N. peacekeeping at 26.94%; however, since 1994 Congress has capped the U.S. payment at 25% due to concerns that U.S. assessments are too high. Congress appropriated $1.37 billion to most U.N. peacekeeping activities for FY2024 (up to the 25% cap). Due to the gap between the U.N. assessment and the 25% cap, the United States has accumulated over $1.1 billion in arrears since FY2017. President Biden’s FY2025 budget request would fund the U.N. peacekeeping operations up to the 25% cap.
