Chinese carmaker BAIC has proposed taking a majority stake in GM's European arm Opel with a bid worth 660 million euros, reprts say.
Beijing Automotive Industry Corp submitted a non-binding offer for GM's German-based unit Opel late on Thursday, just before a deadline for prospective buyers, according to China's Guangzhou Daily newspaper, the Financial Times and Dow Jones Newswires.
The Chinese company's offer could put pressure on negotiations already underway for Opel.
Russian state lender Sberbank is also in the bidding in partnership with Canadian auto parts manufacturer Magna International.
The German government in May announced a rescue plan for Opel in which 35% of the firm would go to Sberbank and 20% to Magna, but talks have since become bogged down.
RHJ International, a Brussels-based industrial holding, has also made a non-binding offer, according to the Financial Times.
Fiat is also interested in Opel, but has pledged no cash for the stake.
