On November 29, 2015, the European Union and Turkey approved a joint plan under which EU member states will give about three billion euros to Ankara and fast track negotiations for its accession to the 28-nation bloc.
Earlier, the European Commission endorsed the creation of a special 3-billion-euro fund for refugees in Turkey. The EC itself had planned to allocate 500 million to the fund, while the EU countries were to cover the remaining 2.5 billion euros.
Turkey remains a key transit route for refugees. Right now, more than 2.5 million Syrian refugees and 300,000 Iraqi migrants are living temporarily in Turkey; many of them seek to travel onwards to Europe. According to Chancellor Angela Merkel and Foreign Minister Frank-Walter Steinmeier of Germany, Turkey plays a key role in solving the migration crisis in Europe.
