AlQa'dah 4, 1434, Sep 10, 2013, SPA -- Seven Chinese navy ships entered what Japan calls its territorial waters around disputed islets in the East China Sea on Tuesday, the Japan Coast Guard said, according to DPA. The coast guard spotted the vessels near the Japanese-administered Senkaku Islands, which are also claimed by China and Taiwan, where they are known as Diaoyu and Tiaoyutai, respectively. The coast guard ordered the Chinese ships to leave the area, but there was no response, broadcaster NHK reported. The Foreign Ministry lodged a protest with the Chinese Embassy by phone, the Kyodo News agency reported.
