Japan’s coast guard claimed to have spotted four Chinese patrol ships in the waters off the Diaoyu Islands on September 13. But further details of the Chinese patrols still remain unclear.
Japan, in response, has taken actions to beef up its guarding capabilities and keep a lookout.
Japan also declared to have witnessed three Chinese patrol ships approaching to the Diaoyu waters on September 11. Earlier this week, China sent two maritime surveillance vessels to the waters near the Diaoyu Islands to assert the country’s sovereignty.
