Chang'an Automobile (Group) Co, China's fourth-largest automaker, will invest $820 million in 10 major global markets by 2020, a company executive said.

It aims to sell 400,000 vehicles annually outside China by then, said Vice-President Zhu Huarong at the ongoing Frankfurt Auto Show in Germany.

"To make Chang'an a true international automaker, a strong foothold and long-term perspective are crucial," Zhu said.
