Russia is letting it be known that it's ready to walk away from the Gabala radar station it operates in Azerbaijan if the government in Baku doesn't moderate its bargaining position. That's what a source in Russia's Ministry of Defense told Russian media today:
“The Russian military is disappointed by the non-constructive approach from the Azerbaijani side concerning the talks on extending the lease of the Gabala missile radar,” the source said, adding that Moscow would likely leave Gabala if the talks did not move ahead...
The source in the Russian Defense Ministry also said that size of the price increase was unreasonable, since the radar needed a full renovation and the sum Baku was demanding for the lease was comparable to the cost of constructing a new radar.
Recall that Azerbaijan has increased its demands from the current $7 million a year, to $100 million and then $300 million. Unlike many of Russia's installations in the former USSR, like in Armenia, Tajikistan or Ukraine, this one doesn't really come with any security guarantees, so Azerbaijan's interest in it is not great. Meanwhile, Russia has a newer radar in the North Caucasus that fulfillls the same role as Gabala, so it has little interest in ponying up to Azerbaijan. So while this leak by the Russian MoD could just be a bargaining position, it looks like this deal is heading for rejection.
