Nissan Motor Co. shareholders voted in favor of a new board and director committees that are set to ease tensions with partner Renault SA as the companies chart a path forward for their two-decade-old alliance.

Renault SA Chairman Jean-Dominique Senard promised to improve relations with partner Nissan Motor Co., telling shareholders at an annual meeting in Paris that broken trust between the companies is repairable.

Renault SA Chairman Jean-Dominique Senard arrived in Tokyo with a crucial mission: to sell the proposed merger between Fiat Chrysler Automobiles NV and Renault SA to longtime partner Nissan Motor Co.

A merger between longtime alliance partners Renault SA and Nissan Motor Co. would codify a global automotive pecking order dominated by three megaplayers, putting pressure on everyone else to bulk up or risk being left behind. They just need to find a way to agree.
