U.S. assistance is channeled primarily through multilateral agencies such as the Inter-American Development Bank and the World Bank, as well as the U.S. Agency for International Development (USAID). USAID's Eastern Caribbean program has focused on promoting economic growth, combating HIV/AIDS, and protecting fragile ecosystems. Barbados receives counter-narcotics and youth development assistance from the United States under the regional Caribbean Basin Security Initiative and is eligible to benefit from the U.S. military training, exercises, and humanitarian assistance construction program.
