On Saturday morning, a Chinese Navy survey vessel entered Japanese territorial waters off Kagoshima Prefecture, marking the tenth intrusion by such ships in the past year and the 13th if including submarines and intelligence-gathering vessels. The vessel was detected around 6 a.m. local time and left by 7:53 a.m., according to Japan's defense ministry. This incident follows a recent violation of Japanese airspace by a Chinese military reconnaissance plane. In response, the Japanese government lodged a diplomatic protest against China. The continuous intrusions have raised concerns over regional security and sovereignty. The Japanese Maritime Self-Defense Force monitored the vessel's movements during its brief stay.
