"Congressional debate over U.N. [United Nations] funding focuses on the following questions: (1) What is the appropriate level of U.S. funding for U.N. system operations and programs? (2) What U.S. funding actions are most likely to produce a positive continuation of U.N. system reform efforts? The U.N. system includes the parent U.N. organization, a number of affiliated agencies, voluntary funds and programs, and peacekeeping operations. Participating states finance the system with voluntary and assessed contributions. For nearly 60 years, the United States has been the single largest financial contributor to the U.N. system. […] The Administration also requested $780 million in supplemental FY2005 funding for peacekeeping contributions; $680 million was appropriated in FY2005 supplemental funding for U.N. peacekeeping in P.L. 109-13. The $281.9 million request for U.S. voluntary contributions in the international organizations and programs account had included $114 million for UNICEF [United Nations Children Fund] and $95 million for UNDP [United Nations Development Program]. FY2005. P.L. 108-447, the Consolidated Appropriations Act for FY2005, included $1.18 billion for U.S. assessed contributions for international organizations (CIO); $490 million for assessed contributions for U.N. peacekeeping activities (CIPA); and $319,494,000 for voluntary contributions for the international organizations and programs (IO&P) account. In addition, $53 million was included for voluntary contributions to IAEA [International Atomic Energy Agency] in another account."
