evidence: Indeed, China's claims over the Senkakus were not made not until after 1971, when reports suggested deposits of crude oil and other maritime resources around the islands. At least in the 1958 declaration on China's territorial sea, there is no mention of the Senkakus as belonging to China. Their first explicit mention, alongside the Penghu Islands, the Dongsha Islands, the Xisha Islands, the Zhongsha Islands, the Nansha Islands as the island territories of China, was in Article 2, Paragraph 2, of the 1992 Law Concerning the Territorial Sea and the Contiguous Zone, which noted: "The land territory of the People's Republic of China includes the mainland of the People's Republic of China and its offshore islands, Taiwan and all islands appertaining thereto including the Diaoyu Islands; the Penghu Islands; the Dongsha Islands; the Xisha Islands; the Zhongsha Islands and the Nansha Islands; as well as all the other islands that belong to the People's Republic of China."20
