Armenia’s parliament has defied Russia by voting to join the International Criminal Court (ICC).
It means Armenia will now have to arrest Putin should he visit the country, due to an outstanding ICC warrant against him for alleged war crimes relating to the war in Ukraine.
The move adds further strain to the country’s ties with its old ally Russia, which has accused Armenia of acting in an unpartner-like manner.
Kremlin spokesman Dmitry Peskov told a briefing on Tuesday that Moscow regarded Armenia as an ally, but had questions about its current leadership.
Moscow last month called Armenia's effort to join the ICC an "unfriendly step" and the Russian Foreign Ministry summoned Armenia’s ambassador.
Countries that have signed and ratified the Rome Statute that created the ICC are bound to arrest Mr Putin, who has been indicted for war crimes connected to the deportation of children from Ukraine, if he sets foot on their soil.
Armenian officials have argued the move has nothing to do with Russia and was prompted by Azerbaijan's aggression towards the country.
Politicians voted to ratify the Rome Statute by a vote of 60-22. Armenia's president must sign off on the decision, which will come into force 60 days after the vote.
Armenia’s relations with Russia have frayed significantly in recent years.
In 2020, Moscow brokered a deal that ended a six-week war between Armenia and Azerbaijan. It mandated that Armenia cede to Azerbaijan large amounts of territory in and around Nagorno-Karabakh, a part of Azerbaijan with a predominantly Armenian population.
Russia then sent some 2,000 peacekeepers to the tumultuous region and Armenia has accused the troops of failing to prevent recent hostilities by Azerbaijan that led to the country taking full control of the region.
The Kremlin, in turn, has accused Armenian Prime Minister Nikol Pashinyan of precipitating the fall of Nagorno-Karabakh by acknowledging Azerbaijan's sovereignty over the area.
Moscow also blames Armenia for damaging ties with Russia by embracing the West, including hosting US troops for joint military drills.
It remains unclear whether Mr Pashinyan might take Armenia out of the Moscow-dominated Collective Security Treaty Organisation, a group of several former Soviet nations, and other Russia-led alliances. Armenia also hosts a Russian military base and Russian border guards help patrol Armenia's frontier with Turkey.
