BEIJING, July 30 -- On July 30, naval and air units of the PLA Southern Theater Command (STC) conducted readiness patrols in the territorial sea and airspace of China's Huangyan Dao and its surrounding areas. 

Huangyan Dao is an inherent part of China's territory. Since July, forces of the STC have enhanced readiness patrols in the territorial sea and airspace of Huangyan Dao and its surrounding areas. 

Such patrols serve as an effective countermeasure to cope with all sorts of rights-violation and provocative acts. They are meant to resolutely safeguard China's territorial sovereignty and uphold peace and stability in the South China Sea.
