Rome - The heads of seven southern European states will gather in Rome to tackle one of the most stubborn thorns in the EU's side: flows of migrants from war-torn and impoverished countries.
The leaders of Cyprus, France, Greece, Italy, Malta, Portugal and Spain will meet Wednesday in the Italian capital for a short meeting at 7 pm (1800 GMT), followed by a joint press conference and a working dinner.
It will be the fourth meeting of the "Southern Seven" since Greek Prime Minister Alexis Tsipras launched the initiative in September 2016. The group met twice last year, in Lisbon and Madrid.
Issues on the agenda are expected to include the future of the eurozone and efforts to propel growth, employment and investment, as well as preparation for the 2019 European Parliament elections.
- Under pressure -
But from overcrowded reception centres on Greek islands to packed boats heading for Spain, the hottest topic is bound to be migrants.
For Italy, 2017 was a turning point: the country went from large-scale arrivals in the first six months to a sharp drop-off, thanks to controversial agreements in Libya.
Some 119,000 people landed in Italy last year, down 35 percent on 2016.
For its part, Spain saw a notable increase in Algerians and Moroccans sailing in, from 6,000 attempting the crossing in 2016 to nearly 23,000 picked up last year.

In Greece, an accord struck between the EU and Turkey limited the number of arrivals to 28,800 -- six times fewer than in 2016 -- but it did not solve the problem of caring for those who had already made the journey.
The toll of dead or missing in the Mediterranean dropped from nearly 5,000 during crossings in 2016 to 3,116 in 2017, mostly off the coast of Libya.
But the start of 2018 has seen some grim statistics.
Between 90 and 100 migrants were missing after their makeshift boat sank off Libya, the country's navy said late Tuesday. Ten migrants also died last weekend and dozens more are missing after their boat sank.
- Humanitarian corridors -
But apart from rescues at sea, asylum applications -- and the inevitable delays and lengthy appeals -- have placed great strain on some countries.
Greece is struggling to deal with more than 50,000 migrants and refugees, 14,000 of whom are crammed into tents or centres on overcrowded Aegean islands.
In Italy, the authorities have stopped providing details on the number of asylum seekers housed in its reception centres, with the last available figures showing there were nearly 200,000 last spring.
Despite a proliferation of small structures aimed at improving integration, tens of thousands of people are still forced to idle away their days in large centres as a climate of mistrust and racism grows ahead of Italy's general elections on March 4.
Spain has faced a backlash over the state of the detention centres where migrants are held before being expelled.
Anger was fuelled in December after the suicide of an Algerian who was locked up in a prison in the southern region of Andalusia along with nearly 500 other migrants for lack of space elsewhere.
The southern European countries have urged time and again for the migrant burden to be shared across the EU.
"Italy can no longer continue to pay for everyone, in financial terms as well as in terms of political effort," Italian Finance Minister Pier Carlo Padoan said Monday in Brussels.

Interior Minister Marco Minniti -- the man behind the Brussels-backed deal with Libya to block migrants from setting out for Europe -- has urged the EU to follow Italy's lead on humanitarian corridors.
Three days before Christmas, Rome welcomed a group of 162 Ethiopian, Somali and Yemeni refugees who flew directly in from crisis-hit Libya.
Some 10,000 refugees are expected to follow in 2018, Minniti said -- provided they are spread across the EU.
With France also facing a record increase in asylum applications, the migration issue is also expected to figure at a bilateral meeting Thursday between President Emmanuel Macron and Italy's Prime Minister Paolo Gentiloni.
