Drones and key components will be prohibited from being sold, rented or brought into the Chinese capital. Drone owners will also be required to register their devices with the police. China has gradually tightened regulations on drones in recent years, with authorities citing public safety concerns. Drones and flying taxis are part of the so-called low-altitude economy, a strategic priority for China that is expected to generate more than two trillion yuan ($290bn; £217bn) by 2035. In some Chinese cities, drones are a common sight, used for food delivery, agriculture and cleaning buildings. Chinese companies may dominate the global drone market, but the country is becoming one of the most difficult places to fly one. Drones must be registered before they can be brought in and out of Beijing. And if users send their drones out of the city for repair, they need to pick up the device in person rather than have it delivered. All outdoor drone flights in Beijing will also require prior approval, and drone users must complete an online training session and pass a test on drone regulations. (BBC)
