General Motors says it expects sales in China this year to top 3.1 million vehicles. The automaker's China unit president Matt Tsien says, 'Sales growth for GM and its Chinese partners should be slightly ahead of total market growth which is expected to be between 8 and 10 percent.' Last year, GM's sales grew by roughly 11.5% from the previous year. China's auto market has cooled as the economy slowed this year, with sales growth tumbling from 13.9% in May to 8.5% in August. GM and other global automakers are looking to China, the world's biggest auto market by number of vehicles sold, to drive revenues and are investing heavily to appeal to Chinese tastes.
