On August 6, the NDRC announced it will punish two auto giants for monopolistic practices.

Separate anti-trust probes into Chrysler and Audi are drawing to an end, said Li Pumin, spokesman for the NDRC. He did not specify punishments.

Chrysler was investigated by the Shanghai Municipal Development and Reform Commission and Audi by the Hubei Province Price Bureau.

Probes into 12 Japanese companies have also found monopolistic behavior regarding prices of auto parts. The companies will be punished in accordance with the law, Li said.

He also confirmed reports that the Jiangsu Province Price Bureau has separately launched an anti-trust investigation into Mercedes-Benz dealers in five Jiangsu cities.
