On Monday, the PLAN ship was sighted sailing southwest in an area 37 miles southeast of Sumisu Island, part of the Izu Island chain which lies south of Japan’s capital of Tokyo.
Kaiyangxing subsequently sailed between Sumisu Island and the island of Tori-Shima while a P-1 MPA of Fleet Air Wing 4, based at Naval Air Facility Atsugi, monitored the PLAN ship. The releases noted that Kaiyangxing had transited northeast through the Tsushima Strait on April 29.
