Islas Fénix
At one time, the United States laid claim to all the Phoenix Islands under the 1856 Guano Islands Act. However, when Kiribati became an independent republic in 1979, the United States and Kiribati signed the Treaty of Tarawa, under which the United States released all claims to the Phoenix Islands (except for Baker and Howland), which thenceforth became recognized as part of Kiribati.
