EU allocates 6 bn euros sought by Turkey for refugees
After the biggest refugee crisis since World War II in 2015 saw a million people arrive in Europe, Brussels and Ankara agreed in 2016 to resolve the issue.
The two sides have "put an important milestone behind us and (will) now focus on making sure that the refugees and host communities will benefit from our projects."
The issue has put a significant strain on relations between the bloc and Turkey.
He sought to pressure Brussels into providing more support to Turkey in view of the Syrian conflict, especially after violence flared in the northwestern region of Idlib.
The new contracts include supporting health services for migrants and improving the living conditions of the most vulnerable refugees.
They have fled to Turkey since the conflict broke out after anti-government protests in Syria in 2011, with a death toll of nearly 400,000.
Tensions between the bloc and Turkey are high over Ankara's energy exploration in the eastern Mediterranean Sea in waters claimed by Greece.
The bloc said after a European Council summit last week that it plans more sanctions against Turkey.
