Russia’s foreign minister Sergei Lavrov criticised Turkey's comments on Nagorno-Karabakh as “absolutely unacceptable" on a two day visit to the Armenian capital.
President Erdogan of Turkey vowed to stand "side by side with our brothers in Azerbaijan" after fighting earlier this month, the worst in two decades.
Lavrov has played an active role in trying to mediate a ceasefire following He has also visited Baku, the capital of Azerbaijan, earlier this month.
"Karabakh will one day return to its original owner,” said Erdogan while the fighting was taking place between April 2 and April 5. “It will be Azerbaijan's." He has also accused Russia of siding with Armenia in the conflict.
"These were not appeals for peace but for war,” said Lavrov, who was meeting with his Armenian counterpart Edward Nalbandian and president Serzh Sargsyan.
Lavrov and Nalbandian also discussed efforts to make the Armenian economy adapt to its membership in the Eurasian Economic Union (EEU), and economic relations between the two countries.
