Moscow and Ankara reached an agreement on the delivery of Russian S-400 surface-to-air missile systems to Turkey and signed a contract, the cooperation said on Tuesday.

Turkish President Recep Tayyip Erdogan said earlier Tuesday that Ankara had made the first payment for Russian S-400 systems.

"The parties reached agreements on the delivery of the S-400 and signed a contract, Russia is ready to implement it," the statement said.

"The priority right to comment on the contract belongs to the foreign customer. It must be stressed that the delivery of this system to Turkey meets the geopolitical interests of the Russian Federation," the FSMTC said.

The S-400 is Russia's next-generation air defense system. It carries three different types of missiles capable of destroying aerial targets at short-to-extremely-long ranges.
