General Motors Corp. Chief Executive Rick Wagoner said on Tuesday the proposed alliance between GM, Nissan Motor Co. and Renault SA was an interesting idea that would get full consideration from GM leadership.

Wagoner, appointed last week by GM's board to head up consideration of the proposed alliance, told business news channel CNBC in an interview broadcast live from Detroit that he looked forward to meeting Nissan-Renault Chief Executive Carlos Ghosn soon.

Wagoner said it was a misperception that he had opposed the potential tie-up, which has been brokered by billionaire investor Kirk Kerkorian, GM's largest single investor.

It's an interesting idea, Wagoner said. We look forward to sitting down with Carlos Ghosn soon.

Wagoner told CNBC: When this idea was presented, we said we'll take a good look at it. We are looking forward to sitting down. Our minds are completely open.
