EU leaders have said an emergency summit on migration was positive but produced no firm conclusions.
Spanish Prime Minister Pedro Sanchez said the talks had not resulted in any decision on how to tackle the crisis but it had been agreed countries needed to work together.
Mr Sanchez said the meeting, involving the heads of 16 EU countries, were “frank and open” but “we don’t have any concrete consequences or conclusions”.
He added: “Everyone agreed on the need to have a European vision, a common position on a common challenge.”
The meeting followed the Italian government’s refusal to let the rescue ship Aquarius, carrying 629 people on board, dock in its ports. Spain agreed to accept the migrants in Valencia earlier this month.
At the meeting, Italy came up with a 10-point plan and said the burden of migrants had to be shared by all member countries.
The plan, presented by Italy’s Prime Minister Giuseppe Conte, sought more EU support to help the Libyan coast guard patrol its coasts more effectively to stop migrant boats.
The plan argues that existing European asylum rules are obsolete.
The Italian proposal says other European countries must create welcome centres for asylum seekers so the burden is shared.
It also calls for EU investment in migrants’ home countries to give them an incentive to stay.
