Congressional Research Service R44268

U.S. assistance to Vietnam for the environmental and health damage attributed to a dioxin contained in Agent Orange and other herbicides sprayed over much of the southern portion of the country during the Vietnam War remains a significant bilateral issue. Between fiscal years (FY) 2007 and 2020, Congress appropriated nearly $333 million to address these two issues. This includes $45 million in Department of Defense funds transferred to the Secretary of State, for use by the U.S. Agency for International Development, for the dioxin clean-up at the Bien Hoa airbase.
