China is way ahead here. There's now a Ministry of the Low Altitude Economy.[1] There's a Low Altitude Flight Service System, which is air traffic control for drones and flying cars. There are licenses for drone operators, categories of license, (advanced licenses require a flight exam), etc.

China hasn't had much general aviation. There are very few private aircraft. So there was nothing like the US's FAA Flight Service Stations. Plans to change that started in 2018, as a new design, mostly automated. That system also handles drones above 120 meters, or is supposed to.
