China is now the world's largest e-vehicle market. The government's industrial policy includes subsidies for producers that drive down costs and make cars affordable.

This video from the Wall Street Journal looks at the rapid growth of electric vehicles in China. In many places, getting a licence plate for a standard petrol or diesel driven car has literally become a lottery; no such restrictions operate with e-vehicles. Beijing's goal is to be selling 15 million e-vehicles a year by 2030 and for two Chinese companies to become globally-scaled producers over the same period.

Foreign auto-makers are planning investment into China's e-vehicle market and will provide stiff competition for local suppliers.
