Zhenbao Island (Chinese: 珍寶島; pinyin: Zhēnbǎo dǎo; literally "Rare Treasure Island") or Damansky Island (Russian: о́стров Дама́нский) is an island in the Ussuri River, on the border between the Russian SFSR and the Manchurian SSR, long disputed between the Soviet Union and China. In 1969, potshots over the island led to the Sino-Soviet War.
