The United States has had relations with São Tomé and Príncipe since 1975, and has offered millions of dollars in financial aid packages to São Tomé and Príncipe. The financial aid packages were designed to develop the country's infrastructure and improve its fiscal, tax and customs administration. In addition, in recent years, some US Coast Guard ships have visited São Tomé and Príncipe, providing medical and military training to soldiers from São Tomé and Príncipe. In 2002, the US had plans to establish a small military base on the island of São Tomé. São Tomé and Príncipe accepted the construction of the base, but the plan was canceled due to US political and financial issues. In 1992, the US federal government broadcaster, Voice of America, and the government of São Tomé signed a long-term agreement to establish a relay broadcasting station in São Tomé. Voice of America currently broadcasts to much of Africa from this facility.
