CHELSEA, Michigan - Chrysler Group LLC is "aggressively" exploring the possibility of building more vehicles in China, where the company is on track to sell 40,000 cars and trucks this year, an executive said on Thursday.

The US automaker, which is managed by Italy's Fiat SpA, could build cars and trucks in China through a joint venture between Fiat and Guangzhou Automobile Group Co Ltd (GAC).

By taking advantage of the joint venture, Chrysler can expand more quickly in China. Last year, the automaker sold 31,000 vehicles in the country, the world's largest auto market, where 18 million vehicles were sold in total.
