China is pushing into European markets - and striving for ever greater military power. This has already had an impact on the internal and external security of Western countries. How dependent is Germany on China? Fancy some iced tea? It'll be delivered by drone. A tree falls onto the road? The driverless taxi swerves out of the way. The rapid development of artificial intelligence and automation in the megacity of Shenzhen shows how high-tech China is integrating innovation into everyday life. Digitalization is everywhere, in a country where administrative procedures are carried out via mobile phone. But the example of Shenzhen also shows that western countries are in danger of being left behind by China in key technologies such as AI, robotics and electric cars. Behind all this advancement lies a great deal of state planning - as well as possible attempts to exert influence.
