AKIPRESS.COM - Russian energy giant Gazprom will be compelled to switch over to prepaid gas deliveries to Ukraine or completely cut off natural gas supplies, if the country further violate its terms of payment, according to Russian President Vladimir Putin's open letter to 18 European leaders, RIA Novosti reported.

Putin, however, underlined this was undoubtedly an extreme measure.

Talk of a gas cutoff came as Ukraine again defaulted on its gas debt in March, swelling past the November record of $1.45 billion.

Putin explained that Gazprom’s decision to switch to upfront payments for gas stemmed from Ukraine’s inability to pay its debts, despite unprecedented price cuts that Kiev had been recently enjoying.

“I would like to draw your attention to the fact that in March there was still a discount price applied, that the price was $268.50 per 1,000 cubic meters of gas. And even at that price, Ukraine did not pay a single dollar,” the president said.

Putin also pointed to a whole string of discounts that Ukraine had been granted over the years, slashing Ukraine’s gas bill by almost a third. But the country continued to violate its contract obligations, prompting Gazprom to rethink its delivery strategy, the Russian leader said.

The president said that uninterrupted gas transit to Ukraine would require the country to pay Russia about $5 billion upfront in the near future, before the state-run energy company pumped 11.5 billion cubic meters of gas into Ukraine’s underground storage facilities.

Putin also noted the European Union was expected to own up to its pledge to help Ukraine out.

“Russia cannot and should not unilaterally bear the burden of supporting Ukraine’s economy by providing discounts and forgiving debts and, as point of fact, using these subsidies to cover Ukraine’s deficit in its trade with EU member states,” the letter said.

Putin called on the country’s EU partners to join consultations at the ministerial level to help Ukraine’s economy out of the woods.
