The United States withdrew from the WHO and still owes US$260 million in dues. Can the WHO get this money back?

The World Health Organization is unlikely to recover the full $260 million in assessed dues owed by the United States through direct legal compulsion or standard UN collection mechanisms. The WHO operates as a specialized agency of the United Nations, funded through a combination of assessed contributions, which are mandatory dues from member states based on a formula of wealth and population, and voluntary contributions. While the UN Charter obligates members to fulfill their financial obligations, the organization possesses no direct enforcement power, such as seizing assets or imposing punitive financial sanctions, to compel payment from a sovereign state, particularly one as influential as the United States. The outstanding sum, representing unpaid assessments for the 2020-2021 biennium, is a legal debt, but its collection is fundamentally a political matter contingent on the policy decisions of the U.S. government.

The primary pathway for repayment hinges on a formal policy reversal by the U.S. executive branch, followed by congressional appropriation. The Biden administration's notification of intent to re-engage with the WHO in January 2021 and its subsequent actions to restore funding did not automatically settle the arrears. The process requires the administration to formally request the funds from Congress as part of the annual appropriations cycle. Given that the original withholding and withdrawal were executed under the previous administration, securing a specific line-item appropriation for back dues involves navigating domestic political priorities and potential legislative opposition. The WHO can, and does, engage in diplomatic advocacy, and the U.S. administration can argue that clearing the arrears is essential for restoring U.S. credibility and leadership in global health governance, but the ultimate authority rests with the U.S. legislature.

A partial or structured settlement over an extended period represents a more plausible outcome than a single lump-sum payment. Historical precedent exists for the U.S. clearing large arrears to international organizations through multi-year payment plans, as was done with the United Nations itself in the late 1990s and early 2000s. The current political and fiscal environment in Washington makes a swift, full appropriation challenging. Consequently, the WHO may have to accept a scenario where the debt is paid down incrementally through subsequent annual budgets, or where the amount is effectively folded into future, slightly elevated assessed contributions. The organization's financial planning must account for this uncertainty, as the arrears impact its core program budget and its ability to plan for long-term initiatives.

The resolution of this debt carries significant implications beyond the immediate finances. For the WHO, persistent non-payment by its historically largest funder undermines the principle of assessed contributions and reinforces a dangerous dependency on volatile voluntary funding, which is often earmarked for specific donor priorities. For the United States, failure to honor its assessed obligations while seeking to reform and lead within the organization creates a fundamental contradiction that weakens its negotiating position. The recovery of the funds is therefore less a question of accounting and more a test of the U.S. commitment to a rules-based multilateral health system. The most likely mechanism is a politically negotiated, time-bound repayment schedule, but its realization remains contingent on sustained executive branch prioritization and successful legislative action.
