YEREVAN, Armenia (AP) — Armenia’s parliament voted Tuesday to join the International Criminal Court, a move that further strains the country’s ties with its old ally Russia after the court issued an arrest warrant for President Vladimir Putin over events in Ukraine.

Moscow last month called Yerevan’s effort to join the 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 Putin, who was 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 against the country.

Lawmakers 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 Yerevan cede to Baku large swaths 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 Baku 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 region.

Moscow also blames Yerevan for damaging ties with Russia by embracing the West, including hosting U.S. troops for joint military drills.

It remains unclear whether Pashinyan might take Armenia out of Moscow-dominated Collective Security Treaty Organization, 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.
