Chinese military conducted routine patrols in the South China Sea from August 3 to August 4, said a spokesperson on Monday.

China took the the action in response to the moves by the Philippines to enlist countries outside the region for so-called joint patrols and undermined peace and stability in the region, said Tian Junli, spokesperson for the Chinese People's Liberation Army Southern Theater Command.

The forces under the Southern Theater Command will remain on high alert and resolutely safeguard national sovereignty and maritime interests, Tian said, adding "All military activities that seek to stir up trouble or create flashpoints in the region are under full control."
