United Nations Issues: U.S. Funding of U.N. Peacekeeping 
For FY2022, President Biden requested $1.93 billion for 
as the “Helms-Biden Agreement,” which established 
CIPA (a $472 million increase over enacted FY2021 
conditions under which some U.S. arrears, including 
funding of $1.46 billion).The request would fully fund U.N. 
peacekeeping arrears, were paid. Since the enactment of

Department has no plans to repay these arrears. As 
previously noted, the United States has also accumulated 
about $920 million in new cap-related arrears between since 
FY2017 and FY2020. Some U.S. policymakers disagree 
about the status of peacekeeping arrears and argue that they 
should be paid, while others do not recognize them as 
arrears and claim the United States is under no obligation to 
pay them. Some have also raised concerns about the impact 
of arrears on the effectiveness of U.N. peacekeeping.
