SHANGHAI GM, the joint venture between SAIC and General Motors, revealed yesterday that it was one of the companies questioned in an investigation into monopoly practices in the auto industry in China.

“The company assisted with the industrywide research and investigation by the National Development and Reform Commission, but that’s all past tense,” a public relations officer with Shanghai GM told Shanghai Daily.

He declined to reveal when the investigation into Shanghai GM ended or what conclusion was reached by the authority.
