The study, which Eurosam announced on the sidelines of a meeting in Paris of French President Emmanuel Macron and his Turkish counterpart Tayyip Erdogan, is to lay the ground for a development and production contract.
"One can not permanently implore and wait to be finally included", he said, adding that frustration over the European Union stance might tempt Ankara to turn its back to Europe.
In his remarks at the joint news conference, Macron said "two-facedness" in Turkey-EU ties should come to an end.
Commenting on the possibility of Turkey turning its back on Europe he added: 'One can not permanently implore and wait to be finally included'. "When it comes to saying why, the European Union is not really capable of giving reasons", Erdogan said.
During the exchange, the authoritarian Turkish leader, who ordered the arrest of up 55,000 security force members, judges, academics, journalists and activists in the wake of the 2016 failed coup, said his country was "exhausted" after 54 years in the "antichambre" of the EU. Local and global rights groups have accused Ankara of using the putsch bid as a pretext to silence opposition in the country.
Protests over deteriorating press freedoms and human rights abuses in Turkey greeted Erdogan upon his arrival. Well, in Turkey, our judiciary is independent.
Turk Eximbank said in a statement the deal also aims to increase access of Turkish firms to additional funding sources and to make them more competitive.
For his part, Macron said "democracy must be strong against terrorism because the legitimacy of the state means it must protect its citizens".
Ties between Turkey and Europe worsened previous year amid mass arrests and firings carried out by Erdogan's government following a July 2016 coup attempt.
She added that Macron "raised the issue of human rights" but also noted that "he is very pragmatic".
"As France, we believe that future of Turkey and Turkish people should be in Europe", Macron said.
