MAUBEUGE, France/PARIS (Reuters) - France's Renault RENA.PA said it will build new Nissan and Mitsubishi vans at its domestic plants, raising investment in the country as it explores closer integration of the three-way carmaking alliance with government backing.

The announcement, timed to coincide with a plant visit by President Emmanuel Macron, “underlines the importance of France for the alliance”, Renault-Nissan-Mitsubishi said on Thursday.

Renault will build a new Nissan 7201.T NV250 delivery van at the northern Maubeuge factory, on an architecture shared with its own Kangoo model that includes an electric version, the alliance said in a statement.

A larger Mitsubishi 7211.T van will also be produced in Sandouville, western France, alongside Renault's Trafic. The move raises Renault's announced investment in France this year to 1.4 billion euros ($1.6 billion), the companies added.

Under pressure from the French government, the carmaker’s biggest shareholder, Renault boss Carlos Ghosn agreed this year to pursue a closer tie-up with Nissan in what is likely to be his last four-year stint as chief executive.

Renault currently owns 43.4 percent of Nissan, which in turn holds a non-voting 15 percent stake in its French parent and 34 percent of Mitsubishi Motors.

Ghosn has previously said a full merger is possible only if France gives up its 15 percent Renault holding - a step the government has been reluctant to entertain without clearer safeguards on French jobs and other industrial interests.

The investment will eventually boost Renault’s sales to partners - one measure of its financial benefit from the alliance - which fell by 358 million euros in the last quarter, partly reflecting Europe’s diesel sales decline.

France was chosen for the vans investment because “the Maubeuge and Sandouville factories offered the most attractive solution, thanks to their competitiveness”, Ghosn said.

“Within the alliance, Renault Group’s global expertise in light commercial vehicles generates synergies that benefit all of our customers,” he added.

The new Mitsubishi van will be exported from Sandouville to Australia and New Zealand, under the plans announced on Thursday.

The new Kangoo and Nissan NV250 will bring 200 new jobs and 400 million euros of additional investment to Maubeuge, in addition to 50 million previously announced for the electric version.
