German luxury carmaker Daimler will enlarge its management board to put a top executive in charge of its troublesome Chinese car business, a German magazine reported on Sunday.

The additional eighth executive board seat will be created at the group's upcoming supervisory board meeting, weekly Der Spiegel reported, without specifying its sources.

A Daimler spokesman declined to comment.

Daimler's flagship car brand Mercedes lags larger German premium names BMW and Audi in China.
