The CCG vessels took necessary measures to warn and expel it in accordance with the law, said Jiang Lue, a spokesperson for the CCG.

Noting that Diaoyu Dao and its affiliated islands are China's inherent territory, the spokesperson urged the Japanese side to immediately stop all infringement and provocative acts in relevant waters.
