once a city of bicycles, china’s roads are flooded with cars these days. the chinese government seems hell-bent on encouraging people to buy private cars, and competition is among the international giants rather than between foreign and local manufacturers. volkswagen, for example, for the first time sold more cars in china than in germany this past year. but china is expected to surpass japan to become the second-largest automaker in the world. estimated grow: from 24 millions of cars in 2003 – to 56 millions in 2010 – and to 130 millions 2020.
