Speaking after the weekend rescue of nearly 6,000 migrants in the Mediterranean, Foreign Minister Paolo Gentiloni said promises made at last month's EU summit after a migrant boat disaster left 750 dead had to be honoured.
"The EU summit finally confirmed the European character of the migrant issue in the Mediterranean but now we need meaningful steps," Gentiloni told the European Commissioner for Migration, Dimitris Avramapolous, in a telephone conversation, the foreign ministry said.
"In particular, as well as the reinforcement of (border agency) Frontex, Italy expects an extraordinary economic commitment from the European Union to help it meet the urgent needs linked to the reception of migrants.
"A European emergency cannot continue to have only Italian responses."
Gentiloni's outburst came on a day when more than 3,000 migrants landed in southern Italian ports, most of them having been rescued by the country's coastguard or navy on Saturday or Sunday.
A baby girl born on board the Italian navy patrol ship Bettica was among them. Her mother had gone into labour just before leaving Libya aboard one of four barely seaworthy boats whose occupants were rescued by the Bettica.
Mother and baby were transferred to hospital on arrival but were both reported to be doing well, the navy said.
Not everyone was so lucky. At least ten migrants died, adding to an estimated total of more than 1,750 people who have perished in the waters between Libya and Italy since the start of this year.
This weekend's surge in the number of boats leaving Libya was put down to the fine weather and calm sea conditions and will have confirmed the fears of Italian officials who anticipate a record number of arrivals on their southern shores between now and September.
Last year's total of 170,000 was already unprecedented and current trends point to that figure being exceeded in 2015.
Among the ships involved in rescue ops at the weekend was the Malta-based M.Y. Phoenix, run jointly by private body Migrant Offshore Aid Station and Medecins Sans Frontieres/Doctors Without Borders.
The Phoenix, on its first mission of the year, was involved in the rescue of more than 470 people between Saturday and Monday morning, including several pregnant women and babies and a total of 45 children.
MSF doctors treated migrants suffering from injuries sustained during beatings by people smugglers and others suffering from conditions including diabetes, dehydration and skin infections, as well as carrying out checks on the pregnant women.
MSF's Will Turner added: "The boat was absolutely crammed full. As the men, women and children we rescued curled up under blankets to sleep, there wasn't a centimetre to spare. The scale of this crisis is just heartbreaking. I wish we could do more."
