European leaders are descending on Armenia for two unprecedented summits in a country long considered Russia's closest ally in the South Caucasus.
The symbolism for this country of fewer than three million people is hard to overstate; Armenia is a member of Russian President Vladimir Putin's Eurasian Economic Union, and Moscow hosts a military base on Armenian soil.
On Monday, more than 30 European leaders and Canada's prime minister will take part in a European Political Community (EPC) summit in the capital Yerevan.
Tuesday will then see the first ever bilateral EU-Armenia summit, attended by European Commission President Ursula von der Leyen and European Council President António Costa.
Armenia is heavily dependent on Russia for energy resources. It buys Russian gas at a preferential rate - which Putin made a point of spelling out when Prime Minister Nikol Pashinyan visited Moscow on 1 April.
