French President Emmanuel Macron and Italian Prime Minister Paolo Gentiloni agreed to work to reform the European Union during a working dinner in Paris on Sunday.
Macron's victory over Eurosceptic Marine Le Pen in France's presidential election this month, gives "hope and faith in Europe", Gentiloni said at the Elysée presidential palace before the dinner.
But he agreed with the French president's campaign call for a Europe that is "stronger and closer to its citizens".
While Macron has called for a eurozone budget, finance minister and parliament, the Italian leader called for "fiscal and banking union".
"It's not an immediate prospect but it's important to begin working in that direction," he said.
Macron, who has already met German Chancellor Angela Merkel and European Council President Donald Tusk, called for a "real revival of our European perspectives", including a roadmap for a euro investment zone that would "reduce the differences between our economies".
He also noted the "challenges" that Italy faces in relation to migration, admitting that the rest of Europe did not react quickly enough to when it sounded the alarm on the question.
