BRUSSELS - Italy is blocking a European Union plan to provide Turkey with 3 billion euros in aid in exchange for a commitment to stem the flow of migrants into Europe, two European officials said on Thursday.

The move marks a further escalation in Italy’s combative position on EU issues. Prime Minister Matteo Renzi blasted German Chancellor Angela Merkel at an EU summit in December over EU policies on energy, banking and migration.

Since then, Italy has reiterated its opposition to the funding of the EU plan to stem migrants coming to Europe from the Middle East and Asia through Turkey, officials said. The plan is strongly backed by Germany, which is the final destination of most. “There is only one member state that still has objections against the funding for Turkey. We do not understand why Italy is blocking it,” a European diplomat said.

Germany’s Finance Minister Wolfgang Schaeuble is expected to raise the issue at Friday’s meeting of EU finance ministers in Brussels, a diplomat said. The draft plan foresees that one third of the 3 billion euros should come from the EU budget and the remaining 2 billion from EU states.

Talks are continuing on how the national funding would be treated under EU deficit rules. Italy is currently in talks with the EU Commission on whether it can be granted more fiscal leeway in its 2016 budget. EU states gave initial backing to the aid plan at a summit with Turkey in November and the EU summit last month.

“The EU is now seen as backtracking. We need to solve this urgently so we can credibly negotiate with Ankara to stem the flow,” the EU source said. There was no immediate comment from the Italian government.

Obama came to office in 2009 vowing to shutter the facility, which opened under his predecessor George W. Bush to hold suspects after the September 11, 2001 attacks and became known for harsh interrogation techniques that some have said were tantamount to torture.

Inmates were called “enemy combatants” and denied standard US legal rights, meaning many were held for years without charge or trial.

Some figures have estimated that up to 30 percent of released detainees return to militant groups with the aim of carrying out attacks on Western targets.

In his final state of the union address on Tuesday, Obama again urged Congress to help him close the detention facility. “It’s expensive, it’s unnecessary and it only serves as a recruitment brochure for our enemies,” he said.
