PARIS — The leaders of France and Germany will meet next week and plan to push for fundamental changes to the European treaty governing the currency shared by 17 nations, President Nicolas Sarkozy said Thursday. Sarkozy said in a speech in the southern port city of Toulon that during their meeting in Paris on Monday he and German Chancellor Angela Merkel will unveil proposals to try to lift Europe out of its debt crisis and “guarantee” its future.

“France will push with Germany for a new European treaty refounding and rethinking the organization of Europe,” Sarkozy said. “The Maastricht Treaty has revealed itself to be imperfect,” Sarkozy said, referring to the pact that led to the creation of the euro currency in 1999.
