Xinhua recently reported that Yang Yujun, spokesperson for the Chinese Defense Ministry, announced at a press conference that the Japanese Navy has performed intensive following, monitoring, and intelligence gathering whenever the Chinese Navy was in the middle of a military exercise mission in the Western Pacific high seas. China officially protested against the Japanese Navy’s behavior. However the Japanese Defense Minister stated on November 1 that he was “completely unable to understand” China’s reaction as international law permits Japan’s activities, so they are therefore fully lawful. The Japanese government expressed the intent to continue to pay attention to China’s military activities. Yang Yujun also warned that Japan’s recent activities have frequently “produced a war-time atmosphere.”
