SHANGHAI--A pricing regulator in China said Thursday it has levied a 350 million yuan ($56 million) fine on Daimler AG's (DAI.XE) Mercedes-Benz for its monopoly practices.

Mercedes had conspired with its dealers on car and spare-part prices, which hurt consumers' interests, the regulator in the eastern province of Jiangsu said in a statement.

Some dealers for Mercedes in Jiangsu province received a combined fine of about 7.9 million yuan, the statement said.

The announcement came amid a broad investigation into foreign auto makers in China by antitrust officials, mainly for the way they sell spare parts and after-sales services.

In September, China levied a total of $45.8 million in fines against Audi AG and Chrysler for allegedly overcharging Chinese consumers for cars and after-sales services.
