Erdogan left Brussels empty handed on Monday.
After about 2 hours of meetings with EU officials.
The EU expects the implementation of the existing agreement on migration, which included preventing illegal immigration in to the EU from Turkey and funding to help refugees already in Turkey.
Erdogan says that the EU has broken that agreement and he is looking for a string of other benefits too. Including updating the customs union, visa free travel for Turks in the shengen area and support for his plans in Syria.
