Putin squeezes Armenia as Russia seeks to retain global clout

President Vladimir Putin has read long-term ally Armenia the riot act: persist in wanting to join the European Union and you can kiss goodbye to cheap Russian oil and gas.
The Russian leader issued the warning before a parliamentary election in Armenia on Sunday, which polls suggest the party of Western-leaning Prime Minister Nikol Pashinyan will win.
It is not an empty threat. Armenia, a landlocked country of 3 million with centuries-old ties to Russia, is highly dependent on Moscow, which has imposed temporary bans on important Armenian exports before the vote.
