Socotra Rock, also known as Ieodo (Korean: 이어도; Hanja: 離於島; MR: Iŏdo) or Suyan Islet (simplified Chinese: 苏岩礁; traditional Chinese: 蘇巖礁; pinyin: Sūyán Jiāo), is a submerged rock 4.6 metres (15 ft) below sea level (at low tide) located in the Yellow Sea. International maritime law stipulates that a submerged rock outside of a country's territorial sea (generally 12 nautical miles) cannot be claimed as territory by any country. However, the rock is the subject of a maritime dispute between China and South Korea, which consider it to lie within their respective exclusive economic zones.
