The "Reassessing the United States-Tanzania Bilateral Relationship Act" aims to address significant concerns regarding Tanzania's democratic trajectory and human rights record. Congress finds that Tanzania's reliability as a partner is in question due to ongoing political repression, violations of religious freedom, and irregularities in the October 2025 general elections. Incidents like political abductions, politically motivated trials of opposition figures, and the killing of citizens during protests highlight a severe undermining of democracy. The bill mandates the Secretary of State, in coordination with other agencies, to conduct a comprehensive reassessment of the bilateral relationship. This reassessment must analyze Tanzania's democratic priorities, propose necessary democratic reforms, and evaluate U.S. security assistance to ensure adherence to human rights. It also requires an assessment of the impact of political unrest on U.S. business and an evaluation of Tanzania's relationship with China, including military, economic, and political cooperation. A report detailing these findings must be submitted to Congress within 90 days. Furthermore, the bill requires a report within 180 days identifying Tanzanian officials responsible for specific human rights abuses, such as abductions, censorship, religious freedom violations, and extrajudicial killings. The President is then authorized to impose sanctions on these individuals, including asset blocking and visa ineligibility. The bill also prohibits certain U.S. security assistance, grants, loans, and Millennium Challenge Corporation funds to Tanzania. These prohibitions can be terminated if Tanzania enacts electoral reforms, releases political prisoners, holds officials accountable for abuses, and ceases political intimidation. Exceptions to these prohibitions include humanitarian assistance, health assistance, and aid supporting democracy, human rights, governance, and civil society in Tanzania. Sanctions also have exceptions for humanitarian transactions, international obligations, law enforcement, intelligence activities, and the importation of goods.
