There has been a renewed flare-up in tension between China and Japan over disputed islands in the East China Sea.

Three Chinese maritime surveillance vessels have entered Japan's territorial waters around the Japanese-controlled Senkaku Islands, known as the Diaoyu Islands in Chinese.

This follows further incursions by Chinese vessels into Japanese waters on Monday and Tuesday.
