ADU DHABI, February 20. /TASS/. Turkey is interested in purchasing Russian S-400 missile systems, talks on possible supplies are underway, Sergei Chemezov, CEO of Rostec state corporation, said on Monday.

"Turkey is interested in S-400 systems. Talks are underway. The key issue is financing," he told journalists on the sidelines of the IDEX 2017 international defense exhibition.

In November 2016, Turkey’s Minister of National Defense Fikri Isik said Ankara was in talks with Moscow on possible purchase of S-400 systems. In late December, the sides held a meeting of the intergovernmental commission on military technical cooperation, which had been expected to touch upon the issue of S-400 supplies.

The first foreign buyer of Russian S-400 missile systems was China. The corresponding contract was reportedly signed in the spring of 2015. According to media reports, the deal’s cost was three billion U.S. dollars.

In October 2016, Russia signed an intergovernmental agreement on S-400 supplies with India.
