BEIJING--Chinese coast guard authorities said it took “necessary control measures” and drove away a Japanese fishing vessel that had entered “territorial waters” around the Senkaku Islands, state media reported.

“We urge the Japanese side to immediately cease all illegal activities in the waters and ensure that similar incidents do not recur,” China Marine Police spokesperson Gan Yu said, according to the report late Thursday.

China calls the islands Diaoyu while Japan calls them Senkaku. The disputed East China Sea islets are claimed by both and have long been a sticking point in bilateral ties.
