In 2016, 40% of the753, 000 EVs sold worldwide were sold in China, about twice as many as the number sold in the United States. Chinese drivers are already big fans of EVs.

Developing EVs is one of many efforts China has made to reduce pressure on its environment. "As China goes, so will the world's auto industry, "the Wall Street Journal said.
