Senior Colonel Xu Chenghua, spokesperson of the PLA Eastern Theater Command (ETC): Since May 27, the ship-borne helicopter of the Dutch frigate HNLMS De Ruyter illegally intruded into the airspace over China’s Xisha Qundao, and then the frigate transited the Taiwan Strait. The PLA ETC dispatched naval and air assets to track and monitor the Dutch frigate throughout its passage, and handled the situation effectively. Forces of the PLA ETC will stay on high alert at all times and resolutely safeguard China’s sovereignty and security, as well as regional peace and stability.
