Nissan Motor Co. plans to invest about $900 million to boost vehicle-making capacity in China by 40 percent by 2021 — part of a 60 billion yuan ($8.73 billion) strategy to become a top three player in the world's largest auto market.

Nissan and its Chinese joint-venture partner, Dongfeng Group, intend to invest the funds to achieve the planned expansion to manufacturing capacity over the next few years, according to a person close to the plan. That would boost Nissan's vehicle production capacity in China to as many as 2.1 million vehicles a year.

The investment is part of a previously disclosed multiyear plan to expand Nissan's sales in China.
