Liancourt Rocks dispute Japan. In 1954, Japan proposed a reference to the International Court of Justice, which South Korea rejected, believing that the Liancourt Rocks are irrefutably South Korean territories, and thus should not be dealt through diplomatic negotiations or judicial settlement between South Korea and Japan. There are conflicting interpretations about the historical state of sovereignty over the islets. Korean claims are partly based on references to a Korean island called "Usan-do" in various historical records, maps and encyclopedias such as the "Samguk Sagi", "Annals of the Joseon Dynasty", "Dongguk Yeoji Seungnam" (), and "Dongguk munheon bigo" (). According to the Korean
Liancourt Rocks dispute of the islands. Japan's Chief Cabinet Secretary expressed concern that military tensions would escalate. In July 2008, the U.S. Board on Geographic Names (BGN) changed the name of the country to which Liancourt Rocks belong from South Korea to Undesignated Sovereignty and also changed the name from "Dokdo" to "Liancourt Rocks". Responding to this change, Gonzalo R. Gallegos, Acting Deputy Spokesman of the U.S. State Department, said on July 28, 2008 that the United States has long maintained a policy stance of neutrality on the islets, and that the latest change does not represent any policy change within the U.S.
