BEIJING — China's top economic planner approved a total of 90 fixed-asset investment projects last year, which helped boost growth.

The National Development and Reform Commission approved the projects worth 775.4 billion yuan (about $122 billion) in investments last year, mainly in the transport, energy, water conservancy and informatization industries.

In December, the commission approved six fixed-asset investment projects totaling 18.5 billion yuan.

The latest data showed that China's fixed-asset investment went up 4.9 percent year-on-year to over 54.45 trillion yuan in 2021, or up 8 percent from the 2019 level.

The country has the potential and incentive to expand effective investment with strengthened fiscal and monetary support, said Ning Jizhe, deputy head of the commission.
