The Caribbean Basin Security Initiative Authorization Act authorizes the Secretary of State and the Administrator of USAID to implement the Caribbean Basin Security Initiative (CBSI) across thirteen beneficiary countries. This initiative aims to significantly enhance citizen safety, security, and the rule of law throughout the Caribbean region by promoting strategic engagement with local governments and civil society. A core purpose is to actively counter the pervasive influence of transnational criminal organizations and local gangs. The bill outlines several critical purposes for the CBSI, including advancing law enforcement and justice sector capacity building, with a focus on combating corruption, money laundering, and various forms of trafficking. It also prioritizes crime prevention efforts for at-risk youth and vulnerable populations, alongside strengthening the security sector's ability to respond to and recover from natural disasters. A key objective is to promote the rule of law and actively counter malign influence from authoritarian regimes like China, Russia, and Venezuela by monitoring security assistance and restricting involvement in potentially obstructive investment projects. The legislation authorizes an appropriation of $88,000,000 annually for fiscal years 2025 through 2029 to support these comprehensive efforts. To ensure accountability, the bill mandates a detailed implementation plan within 180 days, outlining a multi-year strategy, specific benchmarks, and coordination among federal agencies. It also requires annual progress updates on the initiative's achievements and funding, alongside a separate strategy and reporting for natural disaster response and resilience programs.
