Discussions between Renault and General Motors are progressing well, Renault chief executive Carlos Ghosn said on Thursday.

"It is progressing well but it is still too soon to reach a conclusion. Things are going well so far. There is a good atmosphere. We will have a review on where things stand in September and reach a conclusion on the matter by mid-October," Ghosn told Reuters on the sidelines of a conference of businesses organised by French employers group MEDEF.

Ghosn reportedly declined to confirm reports that Ford had contacted Renault to open discussions in case talks with GM fell through.
