Nissan Motor Co. has a nine-year alliance with Renault SA of France, which Ghosn said was working well. He pointed to shared research costs on ecological technology such as electric cars and joint projects to build cars in new markets such as India and Morocco.
Ghosn, who is also Renault's chief executive, has long thought that adding a partner from North America to solidify its position there to its Asian-European alliance makes sense, he said.
"This is for the long term," he told The Associated Press at Nissan's Tokyo headquarters. "But when it comes, then you will know we have been consistent."
