Updates the U.S. statutory framework for addressing Belarus by replacing the Act's findings, restating U.S. policy, expanding and specifying democracy-support programs, strengthening and preserving sanctions authorities, and requiring new intelligence reporting on Belarus’s support for Russia’s war in Ukraine. It also adds targeted definitions and language to emphasize Belarus’s role in Russia’s aggression, require continued international pressure, and authorize specified program activities and reporting for FY2026–2027.

The law directs continued and expanded U.S. support for independent media and civil society, mandates that certain sanctions remain in place until conditions are met, creates new categories of mandatory/discretionary sanctions and waiver rules, and requires an unclassified DNI report (with classified annex as needed) within 90 days on Belarusian military and paramilitary support for Russia, forced transfers of Ukrainian children, weapons procurement, sanctions evasion, and related activities.
