"If the negotiations with Fincantieri don't go well," Bruno Le Maire said in reference to the Italian state-owned shipbuilder, "we will be forced to consider other options, but I hope that won't be necessary".
"We are sister nations, we want to work hand in hand with Italy," Le Maire said in an interview with the Corriere della Sera daily ahead of talks with Italy's economy and economic development ministers.
The French government sparked a row with Italy last week by temporarily nationalising the STX shipyard after backsliding on a deal with Fincantieri agreed by then French president Francois Hollande in April.
The deal gave Fincantieri a controlling stake in the facility in return for which the Italian company gave guarantees on jobs.
But on taking office in May centrist Emmanuel Macron said he wanted to renegotiate and France has since been pushing for a 50-50 split between Fincantieri and STX's French shareholders -- a proposal rebuffed by Italy.
The shipyard, located in the western port of Saint-Nazaire, has turned out some of the world's biggest cruise liners and also builds warships.
"None of our decisions are anti-Italian, they are driven by legitimate concerns over two points," Le Maire said
The first is job protection, the second is keeping shipbuilding skills in France rather than outsourcing to China.
On the eve of Tuesday's meet, Italian Prime Minister Paolo Gentiloni said Rome would not be pushed around.
"Let's see if any fresh proposals are forthcoming. Collaboration between friends, between European countries, is certainly important. We will defend Italian interests calmly but firmly," he said in a television interview.
Italy has made much of the fact that South Korea's STX Shipbuilding -- the outgoing owners -- held a 66 percent stake, but Paris has refused to let Rome hold a 51 percent stake.
Italy's frustration "is understandable, but the economic situation was completely different. The shipyard was in serious difficulty, now it is profitable and has 11 years of orders lined up," Le Maire said.
