Armenian Prime Minister Nikol Pashinyan stated on Friday that Russia has failed to deliver weaponry that his country paid for and that talks are underway to try to find a solution, according to Russian state news agency TASS.

Treaty allies Russia and Armenia have had strained relations in recent months, with Pashinyan accusing Moscow of neglecting to back his nation in its struggle with longtime adversary Azerbaijan over the breakaway province of Nagorno-Karabakh.

Baku’s forces in September recaptured Karabakh, which is viewed internationally as part of Azerbaijan, prompting more than 100,000 ethnic Armenians to flee the territory into Armenia as Russian peacekeepers largely stood by.

“As for the non-provision of weapons and equipment in exchange for payments, of course, there are problems,” TASS quoted Pashinyan as saying during a press conference broadcast online.

“Consultations are underway on mechanisms for solving these problems,” he said, adding that one option might be to reduce Armenia’s outstanding debts to Russia in exchange for the payment already made, given that Moscow also needed weapons.

He gave no details on the arms that Armenia had bought or how much it had paid for them.

Pashinyan also accused Russian state television channels broadcasting in Armenia of violating local rules, saying that consultations with Moscow on that issue were also needed.

Russian state television has repeatedly blamed Pashinyan for Armenia’s loss of Karabakh.

The Armenian premier referred to a bilateral accord between Yerevan and Moscow which stipulates “that no steps should be taken to interfere in the internal affairs of the country, to destabilize the internal political situation in the country”.

Pashinyan has annoyed Moscow in recent months by calling into question Armenia’s alliance with Russia and seeking to deepen ties to Western countries, while also purchasing arms from new suppliers including France and India.
