China and Japan are involved in an increasingly bitter dispute over ownership of a group of uninhabited islets in the East China Sea, called the Senkaku by Tokyo and Diaoyu by Beijing.
China has in the last two months held similar exercises in the Yellow Sea, and also the disputed waters of the South China Sea.
