GORKI, May 12. /ITAR-TASS/. Ukraine is obliged to pay for June gas supplies in advance by June 2, Gazprom’s CEO Alexei Miller stated at a meeting with Prime Minister Dmitry Medvedev.

On Tuesday, Gazprom will issue an advanced gas bill for June gas under a contract and send a notification to Naftogaz, Miller said.

“The Ukrainian side is obliged to pay June supplies by June 2 (because June is a Sunday),” Miller said.

“Ukrainian partners have the money,” Medvedev said, adding that Kiev had already received the first IMF tranche.

Medvedev called on Europe to send a message to the Ukrainian leadership to the effect Russian gas must be paid for. This is precisely the position Prime Minister Dmitry Medvedev asked Energy Minister Alexander Novak to convey to the European partners in the course of future consultations and negotiations with the European commission.

“We have the right to expect that the European partners will send a message to the Ukrainian leadership to the effect that the debts must be paid,” he said at a meeting with Gazprom CEO Aleksei Miller and Energy Minister Alexander Novak.
