GM: Opel Talks Near Completion

But the German government has said it is still talking with other bidders despite the ongoing negotiations with Magna.

Forster was sharply critical of such comments, telling the FAZ "there is too much talk."

"A lot of people are talking who have nothing to say," he was quoted as saying.

Forster said talks with other investors were nowhere near as far along as those with Magna.

"Magna has a very substantial advantage," the FAZ cited Forster as saying.

He said issues over Opel patents have largely been sorted out with Magna, and that the two companies were now talking largely about how the company would operate in Russia.

"Who will be our local partners there? What happens to the GM factories there and the other GM brands in Russia," he said.
