China's largest heavy-duty truck maker Sinotruk has maintained growth in its exports this year despite shrinking overseas demand due to the eurozone debt crisis. It has clinched export orders for more than 30,000 heavy-duty trucks this year, making it the largest exporter of the vehicles in the country. [Photo/Xinhua]
