The nine-dotted line, U-shape line, or nine-dash map (Chinese: 南海九段线; pinyin: nánhǎi jiǔduàn xiàn; literally "Nine division lines of the South China Sea"; Vietnamese: Đường lưỡi bò; literally: "ox's tongue line") refers to the demarcation line used by the government of the People's Republic of China for its claim in the South China Sea, an area including the Paracel Islands (occupied by China but claimed by Vietnam and Taiwan) and Spratly Islands disputed by the Philippines, China, Brunei, Malaysia, Taiwan and Vietnam, who each either claim all or part of the Spratlys, which are believed to sit on vast mineral resources, including oil.[1] According to Chinese sources the line first appeared in February 1948 as an eleven-dotted U-shape line in a map appearing in a private publication in the Republic of China.[2]

According to President Aquino of the Philippines, "Chinas 9-dash line territorial claim over the entire South China Sea is against international laws, particularly the United National Convention of the Laws of the Sea (UNCLOS)".[5] Vietnam also rejected the 9-dotted line claim, citing that it is baseless and against the UNCLOS.[6] In 2010, at a regional conference in Hanoi, Secretary of State Hillary Clinton announced that "The United States has a national interest in freedom of navigation, open access to Asia's maritime commons, and respect for international law in the South China Sea".[7] The United States has also called for unfettered access to the area that China claims as its own, and accused Beijing of adopting an increasingly aggressive stance on the high seas.[7]
