Who is Kandi--- New Chance for China Auto Makers
Kandi was an automobile manufacturer established only in 2003, it formerly specialized in manufacturing mini service vehicles, but profited as little as the size of the vehicles they produced. Three years ago, they found the globe demand for recreation vehicles was huge; they began to produce recreation vehicles with a conception of environment protection and recreation, their annual production value leaped suddenly from tens of million RMB yuan to 5 hundred million yuan, besides, Kandi has listed on the main board of Nasdaq Stock Market.
