President Vladimir Putin and Turkish counterpart Recep Tayyip Erdogan held talks in Istanbul on Monday in which the prospect of supplying Ankara with air defence systems was brought up, Kremlin spokesman Dmitry Peskov told Russian news agencies.
Turkey 's private NTV channel, citing Turkish foreign ministry sources, said earlier this week that Ankara was ready to accept an offer from Russia for a Turkish tender to build long-range air defence systems .
Turkish officials, contacted by AFP, said they had no information about any development.
Putin's visit to Turkey -- his first since the November 2015 downing of a Russian war plane by Ankara sparked the worst dispute between the countries since the Cold War -- saw each side pledge to step up cooperation in all areas including defence and technology.
The Kremlin strongman on Monday hinted that concrete measures would be taken to reinforce defence ties with Ankara.
"We are ready to continue this (military-technical) cooperation and boost it with serious projects of mutual interest," Putin said.
"Proposals from both sides are being studied, and I am certain they have all the grounds to be carried out."
At the time, Turkish officials said Ankara had instead an ambitious plan to build a Turkish-made missile defence system.
