ArmInfo.Armenian President Serzh Sargsyan "has never heard Moscow's response to the question of the sale of arms to Baku," as he realizes that this is his personal  omission. The omission for which he will have to justify himself, believes Sergei Seregichev, an expert at the Institute of the Middle East.

"Sargsyan raises the issue of arms deliveries to Azerbaijan at  meetings with Vladimir Putin periodically, and the latter argues for  the sale to Baku of weapons by the need to keep Baku under its  control." I think that against the backdrop of doubts emerging around  this point after the April escalation in 2016, apparently, gives  Yerevan some guarantees not to place heavy Russian weapons in the  immediate vicinity of the Karabakh border," the expert suggested.

Seregichev is convinced that at the disposal of the Armenian  president there are both copies of military agreements concluded  between Moscow and Baku, as well as all the information, a list of  Russian arms supplied to Azerbaijan.

"The president of Armenia simply does not want to hear and  participate in discussions about these supplies, apparently he  believes that there will be less discussion if he simply says that he  knows nothing about Moscow's response," Seregichev summed up.

Since 2010, Russia has supplied offensive weapons to Azerbaijan worth  $ 10 billion. According to the report of the Stockholm International  Peace Research Institute (SIPRI) only in 2010-2014 the volume of  imports of weapons to Azerbaijan in comparison with 2005-2009  increased by 249%. Only in 2015 Baku allocated 18% for military  articles – up to $ 5 billion of all budgetary appropriations. 85% of  weapons Azerbaijan continues to import from Russia.
