H.R. 2097 would authorize the appropriation of $50 million each year over the 2020-2024 period for assistance to Vietnam, Laos, and Cambodia. The amounts would be used to locate and clear unexploded weapons and to provide humanitarian assistance. The bill also would require the President to brief the Congress each year about that assistance. Using information about similar assistance currently being provided to those countries, CBO estimates that implementing the bill would cost $132 million over the 2020-2024 period; such spending would be subject to appropriation of the specified amounts.
