This legislation authorizes the U.S. government to impose targeted sanctions against foreign individuals and entities that undermine the Dayton Peace Agreement, destabilize Bosnia and Herzegovina, or threaten its territorial integrity and democratic institutions. The bill requires the President to submit a list of sanctioned persons to Congress every 180 days, with sanctions including asset freezes in the U.S., visa revocations, and restrictions on financial transactions through American banks. The legislation also codifies existing sanctions from two executive orders related to the Western Balkans and allows Congress to request determinations about whether specific individuals meet sanctions criteria, with the President required to respond within 60 days. The bill includes exceptions for humanitarian assistance, intelligence operations, and national security activities, and allows the President to waive or terminate sanctions on a case-by-case basis with congressional notification. The entire act and its authorities expire seven years after enactment.
