Greece is stepping up efforts to find allies in the US & Russia as cash reserves run dry while an agreement on additional funding from the country’s euro partners still looks like weeks away.  Finance Minister Yanis Varoufakis met with IMF Managing Director Christine Lagarde & reiterated Greece will repay her institution about €450M ($494M) on Thurs.  He is scheduled to meet with a US Treasury undersecretary for intl affairs before Prime Minister Alexis Tsipras heads to Moscow a day later to discuss food exports.  Greece & euro-area authorities are negotiating a package of measures proposed by the gov to repair the economy, a condition for the release of more bailout funds.  A meeting of euro-region finance ministers on Apr 24 must reach an initial accord on Greece, Varoufakis said.  The ministers & central bankers are scheduled to hold informal discussions that day in the Latvia.  The country won’t default on payments to the IMF this week even as a lack of bailout disbursements has left gov coffers nearly empty, according to a minister.  Prime Minister Tsipras meanwhile will visit Moscow, with Russia ready to discuss easing restrictions on Greek food products . Russia isn’t considering financial assistance to Greece.
