The Xinhua news agency reported Wednesday that the National Development and Reform Commission published on its Web site a draft regulation on "managing the production of alternative energy vehicles and called for suggestions and comments."

Vehicles included are hybrid-electric vehicles, battery electric vehicles, including those that work on solar energy, and fuel-cell electric vehicles.

According to the draft, prototypes can be operated in approved areas; more sophisticated products can be produced in batches for sale only in approved areas; and the most-sophisticated products will have the same status as regular autos.

Firms must obtain the NDRC's permission before beginning production, the draft says.
