Greek Prime Minister Alexis Tsipras (R) and President of the Russian Federation Vladimir Putin give a joint press conference after their meeting in Athens on May 27, 2016. The visit -- Putin's first to the EU since December - comes as the bloc's leaders are to discuss next month whether to renew sanctions on Russia's banking, defence and energy sectors that expire in July.
