Nissan Motor Co.'s top executive Carlos Ghosn pledged Wednesday to rebuild trust in Mitsubishi Motors Corp. and return the loss-making carmaker to profitability, as he was approved by shareholders as the new chairman of the scandal-tainted automaker.

"I pledge to protect shareholder interests and the long-term sustainability of Mitsubishi Motors," Ghosn said at an extraordinary meeting in Chiba of shareholders of the automaker struggling to emerge from a fuel-economy data manipulation scandal.

"I know you will have questions about whether this enlarged alliance will work," he said. "From past experience, I am confident that it will."
