"What we can and what we should discuss during this possible summit is our custom cooperation … cooperation on migration, we have enough topics to justify this kind of initiative like the summit," Tusk said after a Thursday EU leaders’ summit.
An EU source told RIA Novosti that the summit could be held as soon as in January 2017.
In March, Brussels and Ankara worked out and agreed on a deal, under which Turkey pledged to take back all undocumented migrants that had arrived to the European Union in exchange for Syrian refugees on a one-for-one basis. In return, the European Union pledged to provide a total of 3 billion euros ($3.2 billion at the current exchange rates) to Turkey for dealing with refugees, with a possible further 3 billion-euro provision, accelerate Turkey's EU accession process and introduce a visa-free regime between Turkey and Europe.
In November, the European Parliament voted in favor of freezing EU accession talks with Turkey over concerns about Ankara's post-coup crackdown. However, the vote was non-binding and mostly symbolic, which means it would not be supported by the European Commission. The move has been widely criticized in Ankara.
