Germany-based automaker Volkswagen AG's premium brand Audi said in a statement on its website on Monday that the company's executives acknowledged its "antitrust" activities on Friday to the Bureau of Price Supervision and Anti-Monopoly under the National Development and Reform Commission.

The company was investigated by officers in Hubei province for its price controls imposed on local dealers, the NDRC said last week.

"The FAW-Volkswagen Audi Division has taken action immediately and stopped the illegal behavior," said Zhang Pijie, general manager of FAW-Volkswagen, a joint venture between the Chinese and German automakers that makes Audi vehicles.
