JINAN - China National Heavy-Duty Truck Group (Sino) has exported 21,000 vehicles this year, maintaining its position as China's top truck exporter.

The volume represents 40 percent of China's total truck exports, said Yu Youde, a senior manager of the State-owned company, based in Shandong province.

Sinotruck's vehicles are sold in more than 90 countries. It has 160 sales offices and 590 parts and after-sales service points overseas, mostly in developing countries.

The company has established ten assembly lines in southeast Asia and Africa.

Yu said Sinotruck will continue to increase its presence in those regions, where more factories are planned.
