Democratic Party of Japan Secretary General Katsuya Okada cautioned both Japan and China not to resort to extreme nationalism following the recent bilateral spat in connection with the Senkaku Islands.
Recent days have seen a series of large-scale demonstrations staged in China essentially in protest of Japan's control of the Senkaku Islands, which are also claimed by both China and Taiwan.
Japanese protesters have also rallied in front of the Chinese Embassy in Tokyo over China's retaliatory moves after Japan arrested a Chinese trawler captain following the Sept. 7 collisions between his vessel and Japan Coast Guard patrol boats trying to board it near the Senkakus.
