China helicopter operations were also detected and reported near southeastern Taiwan on five consecutive. PLA air activities reported by the ministry around the island are usually dominated by fighter jets and drones. Some 23 PLA aircraft and seven vessels were detected in a 24-hour period starting on Sunday morning, including another helicopter near southern Taiwan. Taipei said 19 aircraft, including the two helicopters, had entered the island’s air-defence identification zone to the north, east and southwest.
