The Philippines and the United States have begun a joint patrol in the South China Sea.

On Tuesday, the military of the Philippines and the United States launched coordinated patrols in the South China Sea. The action might exacerbate tensions further since China has warned the Philippines against doing business with the US. The move coincides with China's assertive behavior in vital waters. According to available intelligence, joint naval and aviation patrols are being conducted in the Batanes Islands area, according to a Philippine military statement.
