Senkaku Islands
Meanwhile, the Japanese-controlled Senkaku Islands are claimed by the ROC as "Diaoyutai Islands" within Toucheng Township, Yilan County and are considered to be part of geographic and provincial Taiwan by the ROC. The Senkaku Islands lie about 186 kilometres from the northeast of Taiwan Island, and situated roughly 330 kilometres from the east of mainland China. They form the westernmost extremity of the "Ryukyu Islands", which Japan administers as Okinawa Prefecture. The PRC also claims the Senkaku Islands as "Diaoyu Islands" as part of its claimed "Taiwan Province".
