China's coast guard enters disputed East China Sea waters.

China's coast guard entered the disputed waters of the East China Sea to counter what it called the incursion of Japanese vessels into Chinese territorial waters. The disputed East China Sea islets claimed by China and Japan have long been a sticking point in bilateral ties. China calls the islands Diaoyu while Japan calls them Senkaku. The patrol comes a day before Japanese Prime Minister Fumio Kishida is set to hold a summit with South Korean President Yoon Suk Yeol in Tokyo.
