Greek PM, Putin discuss boosting co-operation

Athens - Greek Prime Minister Alexis Tsipras discussed boosting co-operation with Russia on a variety of fronts including energy and the economy during a phone call with Russian President Vladimir Putin, the Greek leader's office said on Thursday.

"The Russian president and the prime minister emphasised the need for substantial improvement of the co-operation between Greece and Russia - countries with deep and historic ties - especially in the sectors of economy, energy, tourism, culture and transport," a statement from Tsipras' office said.

Putin has invited Tsipras to visit Moscow on May 9, the statement said, adding that the two leaders also discussed safeguarding peace and stability in Ukraine.

Tsipras, whose new left-wing government ruffled feathers among European partners with comments that suggested Greece wanted to undermine EU policy on Russia, has ruled out seeking aid from Russia.
