MOSCOW, April 29 (Xinhua) -- Russia and Turkey are jointly developing advanced aircraft and helicopter systems and armored vehicle components, Russian state-run arms exporter Rosoboronexport, part of Rostec Conglomerate, said in a statement Monday.

"In addition, Turkey is interested in Russia's latest remote weapon stations, air defense assets of varying ranges, as well as anti-tank guided missile systems," the statement quotes Rosoboronexport's CEO Alexander Mikheyev as saying.

Rosoboronexport will be showcasing the best-selling and promising new products from the Russian defense industry at the 2019 International Defense Industry Fair (IDEF), which will be held on April 30-May 3 in Istanbul, Turkey.

Rosoboronexport is the organizer of a joint Russian display at IDEF 2019, which includes over 450 pieces of weaponry and military equipment from more than 10 domestic defense manufacturers, the statement said.

CEO of Rostec, Sergei Chemezov, said in the statement that Turkey is among the key partners of Rostec and Russia.

Rostec has discussed with Turkey the implementation of a number of critical projects in both military technical cooperation and civil industry fields and is ready for various formats of technology cooperation, including in such high-tech areas as the aerospace, helicopter and power industries, he said.

Turkey, a member of the North Atlantic Treaty Organization (NATO), has signed a 3.5-billion-U.S.-dollar deal to purchase Russian advanced S-400 air defense systems.

Earlier this month, the Pentagon threatened to block the transfer of the F-35 fighter jets to Turkey and remove it from the F-35 joint production program unless Ankara dropped the S-400 deal.

Washington also threatened to reject sales of Patriot missiles to Turkey in case of the latter's purchase of Russian systems.

Turkish Foreign Minister Mevlut Cavusoglu has said that the S-400 purchase was irreversible and his country could buy a second batch of S-400 and look for military aircraft elsewhere if Washington refuses to supply its Patriot.
