The world has changed a lot because China has changed a lot. China’s share of global GDP has risen from a negligible 2% in 1990 to 15.9%. Meanwhile, the other powers have fallen in that period: Japan, from 14 to 5.8%; Europe, from 35% to 21.9%; and the USA, from 27% to 23.9%, according to Weltbank data. So hundreds of thousands of jobs in Germany are now dependent on China. And all over the world, because China today accounts for 1/3 of world growth.
