China is opening up internally. For generations, the hukou system meant the average Chinese national couldn’t freely emigrate within China. Like being geolocked to New York and being unable to relocate to Texas. China did this in part for social control, and in part to prevent huge floods of people from moving to big Chinese cities for jobs before the infrastructure was available. But now development in China is so broad-based, and the infrastructure so reliable, that they are gradually opening the borders *within* China by letting everyone move around. The Soviets also had a system of internal passports. But the new Chinese system is less similar to traditional communism, and more similar to the Schengen region for the EU, or the free migration between the fifty states within the US. In many ways China is moving in the opposite direction from the West, by opening up visa-free travel to China for 50 countries, introducing the K visa for skilled migrants, and gradually shelving the hukou system. The overall trend is towards more free (albeit still controlled) flows of capital and talent within China.(Balaji)
