Renault and Nissan must streamline decision-making in the car-making alliance and boosting the companies' cross-shareholding is not currently in their plans, Renault's chairman said in comments published on Sunday.
Japan's Nissan Motor and France's Renault, together with junior ally Mitsubishi Motors, agreed last week that they would retool the alliance to put themselves on a more equal footing.
