BEIJING -- Sales of electric and plug-in hybrid vehicles more than doubled in the first half of this year in China, compared with the same period a year ago, a trade group reported recently.
With the government set to impose sales quotas for "new energy" cars starting next year, the market is welcoming newcomers and competition is intensifying. U.S. automaker Tesla, which specializes in electric cars, has decided to make cars in China, for example.
