TOKYO (Reuters) - Carlos Ghosn, head of the automaking alliance between Nissan Motor Co and Renault, is considering a review of the capital ties between the two companies, Japan's Nikkei business daily reported on Monday.

Ghosn, who also serves as chief executive of Renault, said in an interview with the newspaper that it was necessary "to consider the views of all interested parties" in reviewing the two firms' cross-shareholding structure, adding that he would implement a new framework by 2022 when his term ends.

His comments follow a Reuters report last month that France's Renault and Nissan were discussing a deal that would see the Japanese automaker acquire much of the French government's 15 percent Renault holding, as a prelude to a merger.

"We are openly considering all options," the Nikkei quoted Ghosn as saying, adding that this included a review of the group's capital structure.

Nissan was not immediately available for comment.

The Renault-Nissan alliance, underpinned by cross-shareholdings, has wrestled intermittently since its 1999 inception with plans for full mergers that have foundered on objections from France, Renault's biggest shareholder.

But with the alliance's main architect Ghosn beginning his final term as Renault CEO, the government has been pressing for a tie-up to secure the future of Renault-Nissan, the world's largest carmaking group by sales last year.

Renault holds 43.4 percent of Nissan but agreed to limit formal control of its larger partner in a 2015 shareholder pact that defused a boardroom standoff with the French government. Nissan currently owns a 15 percent of Renault, but no voting rights.

The Japanese automaker also owns a 34 percent controlling stake in Mitsubishi Motors Corp. (>> MITSUBISHI MOTORS CORPORATION).
