General Motors Co Chief Executive Fritz Henderson said on Tuesday that it was possible a deal on the sale of a majority stake in Opel, its European carmaking arm, could come this week.
"It's quite possible to see documents signed this week," Henderson said.
The comments followed a statement by Opel labour leader Klaus Franz on Monday that he expected GM to sign a contract this week to sell a 55 percent stake in Opel to a consortium including Canada's Magna and Russia's Sberbank.
The two companies have vowed to inject 500 million euros ($739 million) into Opel, aiming to use it to make an aggressive push into the Russian market, and plan to cut about 10,500 European jobs.
Henderson also told a news conference in Shanghai that it was not on his agenda during his trip to China to talk to Chinese regulators about a deal to sell GM's Hummer brand to Chinese machinery maker Tengzhong.
GM finalised a deal with Sichuan Tengzhong Heavy Industrial Machinery last Friday on the sale of its Hummer business, although the deal still faces a number of hurdles including regulatory approvals.
Henderson was also upbeat on the prospects for the Chinese auto market, forecasting it to continue to grow at a significant pace in the future.
GM said last week that its China vehicle sales surged 55.6 percent in the first nine months of this year from year-earlier levels, surpassing forecasts.
