French economy minister Emmanuel Macron reiterated Tuesday that the French government intends to lower its stake in Renault SA to 15% and insisted the government opposes significant changes in the alliance between the French car maker and Nissan Motor Co. The government's decision earlier this year to raise its stake in the French car maker to almost 20% caused tension on the boards of both companies as the move changed the cross-shareholding system underpinning the alliance.
