It is also the largest producer of and market for new-energy vehicles, with more than 500,000 built and sold a year ago.
China has already proposed a plan by which manufacturers have to increase the share of electric and hybrid petrol-electric vehicles to 12 percent by 2020.

The world's second-biggest economy, which has vowed to cap its carbon emissions by 2030 and curb worsening air pollution, is the latest to join countries such as the United Kingdom and France seeking to phase out vehicles using gasoline and diesel.
China will soon unveil a mandatory cap-and-trade credit programme for electric cars, starting the countdown for carmakers to be in compliance with stricter rules on emissions and fuel economy, according to the country's state-backed auto association. Volvo announced that all its cars will be electric or hybrid from 2019.
