国内英语新闻:China says Japan-U.S. security treaty should not harm third-party interests

BEIJING, May 28 (Xinhua) -- As a bilateral agreement, the Japan-U.S. Treaty of Mutual Cooperation and Security should not harm the interests of China and other third parities, said Foreign Ministry spokesman Ma Zhaoxu here Friday.

Ma made the remarks in response to a question about Japan's latest claim over the Diaoyu Islands in a news report.

According to the report, Japan said on Thursday the Diaoyu Islands were a part of Japan and the U.S. would be obligated according to the treaty to engage in military conflicts between China and Japan over the island should they occur.

Ma said China has indisputable sovereignty over the Diaoyu Island and adjacent islets, which have been an inalienable part of China's territory since ancient times.
