Russian President Vladimir Putin bought ice cream for his guest, President Recep Tayyip Erdogan, during a visit to an air show on the outskirts of Moscow on Tuesday.
Before buying the ice cream, Putin and Erdogan jointly inspected the new Sukhoi Su-57 Russian fighter plane and toured the exhibition. , In a move that would raise further tension between the Turks and the West.
Russia this year began supplying Turkey with the S-400 missile defense system, a move that has affected Ankara's relations with its NATO partners and prompted Washington to start excluding it from its F-35 program, which Turkey also planned to buy.
Dmitry Shogayev, head of the Federal Service for Military-Technical Cooperation, said: "A lot of interest has been expressed.
Such talks would infuriate Washington and NATO, especially since Turkey faced many obstacles when it bought the Russian missile defense system "S400".
In mid-July, Washington announced the exclusion of Turkey from the program of manufacture of "F-35", because of fears of exposure to Russian espionage in Turkey due to the presence of the system "S400", which Ankara received its first batch.
