The leaders of France and Italy have said Europe’s Schengen open-border treaty should be revised.
The move by President Nicolas Sarkozy and PM Silvio Berlusconi comes after they met to discuss the recent rise in North African migration to Europe.
Italy has angered France by granting visas to thousands of migrants, allowing them to travel across Europe’s border-free Schengen zone.
About 25,000 migrants have arrived in southern Italy so far during 2011.
Many have fled unrest in North Africa, and among them are thousands of Tunisians hoping to join relatives in France.
Both Mr Berlusconi and Mr Sarkozy are facing domestic pressure from right-wing parties to curb large-scale immigration.
