Turkey and Russia are in the process of signing a new contract for the purchase of additional S-400 missiles in the near future, the Interfax news agency cited the head of Russia's Rosoboronexport arms exporter as saying Monday.
Ties between NATO allies Turkey and the United States were badly strained over Ankara's acquisition of the advanced S-400 Russian air defense system, prompting Washington to remove Turkey from its F-35 Lightning II jet program.
The U.S. argued that the system could be used by Russia to covertly obtain classified details on the Lockheed Martin F-35 jets and is incompatible with NATO systems. Turkey, however, insists that the S-400 would not be integrated into NATO systems and would not pose a threat to the alliance.
Previous talks between Turkey and the U.S. on the purchase of Patriots collapsed over a host of issues, from the S-400s to Ankara's dissatisfaction with Washington's terms. Turkey has said it will only agree to an offer if it includes a technology transfer and joint production terms.
