Turkish President Recep Tayyip Erdogan hopes to receive financial, political and military support from the EU and NATO.

Erdogan will hold talks with EU and NATO leaders. But the Turkish leader will be told he must first stop encouraging migrants to cross his country’s borders into Greece, Reuters reported. 

Tens of thousands of migrants are trying to infiltrate Greece, after Ankara announced on February 28 that it would no longer try to keep them on its territory.

“The events at the Greek-Turkish border clearly point to politically motivated pressure on the EU’s external border,” the head of the European Commission, Ursula von der Leyen, said ahead of the talks with Erdogan in Brussels on Monday. “Finding a solution to this situation will require relieving the pressure that is put on the border,” she told a news conference.

The EU seeks to avoid a recurrence of the migrant crisis of 2015-2016, when over a million people, mainly from the Middle East and Asia, reached the EU through Turkey and Greece. This flow was largely stopped by the 2016 deal, which the EU hopes to save.

“A precondition for any additional EU help should be to stop all support to illegal border crossings and move people away from the border,” a German conservative member of the European Parliament, Manfred Weber, said on Monday.

Erdogan will meet NATO Secretary General Jens Stoltenberg, Ursula von der Leyen and European Council President Charles Michel.
