Well-known Chinese news site Sina recently reported that the Japanese Defense Ministry revealed on November 27, that eleven Chinese military aircraft flew across the East China Sea over the high seas towards the island of Ryukyu. The Japanese Air Self-Defense Force responded with sending emergency flights. According to the details reported by Japanese news agencies such as Yomiuri Shimbun, the Chinese aircraft included an H6 Bomber and a TU154 reconnaissance aircraft. The Chinese airplanes later returned back to China. It is very rare for as many as eleven Chinese military aircraft to approach Japan. The Japanese Defense Ministry is still analyzing the intent of the Chinese Air Force. The last time any Chinese military aircraft approached Ryukyu was in July of this year.
