The German automobile giant Daimler has become the latest multinational company to bear the brunt of a Chinese regulatory inquiry, and an official from the agency that visited the company’s offices in Shanghai said on Wednesday that it was under investigation for “monopolistic behavior.”

The visit to the office on Monday came just a day after Daimler, the maker of Mercedes-Benz cars, said it would cut the price of Mercedes-Benz repair parts sold in China by an average of 15 percent “in response to antimonopoly investigations into the automobile industry” by a Chinese agency, the National Development and Reform Commission.

A Daimler spokesman in Germany confirmed on Tuesday that the Shanghai offices had been searched and said that the company was cooperating with officials. He said Daimler would not comment further on the continuing investigation and declined to give his name, citing company rules.

Separately, Senol Bayrak, a spokesman for Daimler Greater China in Beijing, said by email: “We confirm that we are assisting the authorities in their investigation.” He added: “We are unable to comment further on what is an ongoing matter.”
