Few nominal issues are left to clear up in a generally formalized contract on the delivery of Russia’s S-400 missile systems to Turkey, Turkish presidential spokesman Ibrahim Kalin said Friday.

Turkish President Recep Tayyip Erdogan said this week that Ankara and Moscow had signed a document on supplies of the S-400 Triumf systems.

“The negotiations are coming to an end. This I can clearly state. Minor points relating to the agreement remain to be clarified. However, in general terms, the agreement has already taken shape,” Kalin said as quoted by Turkey’s Anadolu news service.

The Russia-Turkey talks on the delivery of S-400 systems have taken place since 2016. In March, Sergei Chemezov, CEO of Russia’s Rostec Corporation, said Ankara was ready to buy the systems with a loan granted by Moscow. On July 18, Chemezov said technical issues of the contract for the supply of the S-400 systems to Turkey had been resolved, with only administrative ones remaining.
