Other meanings of Diaoyu Islands
Geography
The Diaoyu Islands (also known as the Senkaku Islands in Japanese and the Tiaoyutai Islands in Chinese) are a group of uninhabited islets in the East China Sea, administered by Japan but claimed by China and Taiwan. The archipelago comprises five main islets and three barren rocks, with a total land area of about 7 square kilometers. The islands are situated approximately 170 kilometers northeast of Taiwan, 330 kilometers west of Okinawa, and 200 kilometers east of the Chinese mainland. Their strategic location near major shipping lanes and potential seabed resources has made them a focal point of territorial disputes in East Asia.
The Diaoyu Islands consist of five main islets and three barren rocks, with Uotsuri Island (Diaoyu Dao) being the largest, covering about 4.3 square kilometers and rising to 383 meters at its highest point. The islands are composed primarily of sedimentary and volcanic rocks, with steep cliffs and sparse vegetation. The surrounding waters are rich in fish and other marine life, and the area is a known habitat for the short-tailed albatross, a vulnerable species. The islands have no permanent freshwater sources, which has historically limited human habitation. The climate is subtropical, influenced by the East Asian monsoon, with frequent typhoons in late summer.
The islands have been known to Chinese fishermen and navigators since at least the 15th century, appearing in Ming dynasty records as part of the Ryukyu trade route. Japan claims to have incorporated the islands as terra nullius in 1895, following the First Sino-Japanese War, while China contends that the islands were part of its territory and were ceded to Japan under the Treaty of Shimonoseki (1895) and later returned under the San Francisco Peace Treaty (1952). After World War II, the islands were administered by the United States as part of the Ryukyu Islands, and in 1972 the US returned them to Japan, a move that China and Taiwan have since contested. The dispute intensified in 2012 when Japan nationalized three of the islets, triggering widespread protests in China.
The legal dispute hinges on the interpretation of historical sovereignty and the principle of terra nullius. China argues that its historical records and maps demonstrate continuous administration, while Japan maintains that the islands were uninhabited and unclaimed before 1895. The United Nations Convention on the Law of the Sea (UNCLOS) has been invoked by both sides, particularly regarding the delimitation of the exclusive economic zone (EEZ) and the continental shelf. The islands are also significant for potential oil and gas reserves in the East China Sea, though commercial exploitation has not occurred. Diplomatic efforts have included bilateral talks and the 2008 agreement to jointly develop the Chunxiao gas field, but sovereignty remains unresolved. The US position, while officially neutral, has been criticized by China for its security treaty obligations to Japan.
Beyond the headline dispute, several lesser-known facts enrich the story. The islands are a nesting site for the short-tailed albatross, and in 2019, a Japanese research team discovered a new species of snail, Euhadra senkakuensis, endemic to the islands. The islands also feature in Chinese literature, such as the 16th-century Shunfeng Xiangsong (Fair Winds for Escort), which mentions the islands as navigational markers. In 2016, a Chinese fishing boat collided with a Japanese patrol vessel near the islands, leading to a diplomatic incident. The islands have no permanent residents, but Japanese coast guard personnel rotate through, and occasional visits by Japanese lawmakers have sparked protests. The area is also a known habitat for the endangered loggerhead sea turtle, which nests on the beaches of Uotsuri Island.
The Diaoyu Islands dispute remains a sensitive issue in East Asian geopolitics, with periodic flare-ups affecting regional relations.
