1970年美日協議,美國將二戰時佔領的琉球群島的管轄權移交日本。由於美日皆將釣魚台群島―即日文所謂尖閣群島(senkaku)視為琉球的屬島,遂引發海內外學生保衛釣魚台領土的運動。 In 1970, the United States and Japan agreed to transfer administrative control of the Ryukyu Islands from the U.S. to Japan. Since both countries regarded the Senkaku/Diaoyu Islands as part of the Ryukyus, this triggered student movements in Taiwan and among overseas Chinese communities to defend the territorial claim.
