FYI
Japanese government basic view of Senkaku
From 1885 on, surveys of the Senkaku Islands had been thoroughly made by the Government of Japan through the agencies of Okinawa Prefecture and by way of other methods. Through these surveys, it was confirmed that the Senkaku Islands had been uninhabited and showed no trace of having been under the control of China. Based on this confirmation, the Government of Japan made a Cabinet Decision on 14 January 1895 to erect a marker on the Islands to formally incorporate the Senkaku Islands into the territory of Japan.
Since then, the Senkaku Islands have continuously remained as an integral part of the Nansei Shoto Islands which are the territory of Japan. These islands were neither part of Taiwan nor part of the Pescadores Islands which were ceded to Japan from the Qing Dynasty of China in accordance with Article II of the Treaty of Shimonoseki which came into effect in May of 1895.
Accordingly, the Senkaku Islands are not included in the territory which Japan renounced under Article II of the San Francisco Peace Treaty. The Senkaku Islands have been placed under the administration of the United States of America as part of the Nansei Shoto Islands, in accordance with Article III of the said treaty, and are included in the area, the administrative rights over which were reverted to Japan in accordance with the Agreement Between Japan and the United States of America Concerning the Ryukyu Islands and the Daito Islands signed on 17 June 1971. The facts outlined herein clearly indicate the status of the Senkaku Islands being part of the territory of Japan.
The fact that China expressed no objection to the status of the Islands being under the administration of the United States under Article III of the San Francisco Peace Treaty clearly indicates that China did not consider the Senkaku Islands as part of Taiwan. It was not until the latter half of 1970, when the question of the development of petroleum resources on the continental shelf of the East China Sea came to the surface, that the Government of China and Taiwan authorities began to raise questions regarding the Senkaku Islands.
Furthermore, none of the points raised by the Government of China as "historic, geographic or geological" evidence provide valid grounds, in light of international law, to support China's arguments regarding the Senkaku Islands.
