Turkey is counting on the U.S. to provide it with the technology behind the Patriot missile system before a deal can be reached, Turkish Foreign Minister Mevlut Cavusoglu said.
"For us, the timing of the delivery of the systems is important. We purchased the S-400, but we still need more similar systems," the Turkish foreign minister said.
"Our criteria are also joint production and technology transfer," Sputnik cited him as saying.
A U.S. team wrapped up two days-worth of talks with its Turkish counterparts yesterday. Earlier, Turkish media reported that the U.S. team would look at "express specific concerns" about Turkey's purchase of the S-400s from Russia and how this would affect the "flight safety of F-35 aircraft."
