China has said it overtook the United States to become the world's biggest car and van market in 2009. The China Association of Automobile Manufacturers said 13.6 million vehicles were sold within the country last year. That compares with just over 10 million vehicles in the US, which was previously the world's largest market. Unlike the US, China's figures include heavy trucks, but they added just 650,000 to the total. That meant China was still comfortably ahead in terms of private car sales, which were 53 per cent higher than in 2008. Part of the rise was due to moves by the government to stimulate demand. These included cuts in sales tax for small cars.
