War Zone – Chinese WZ-7 surveillance drones have appeared for two days in a row over the East China Sea, prompting Japanese fighter jets to scramble to intercept them on both occasions. This is the first time that the Japanese authorities have reported intercepts of the WZ-7, one of the most advanced drones in Chinese service, and it could be connected with the recent movements of the Chinese aircraft carrier Liaoning and its supporting task force in the same area.
