“We hope that the EU will play an active role in implementing the provisions of a protocol on deliveries of Russian gas to Ukraine until March 31, 2015,” Nebenzya said.
“We believe that such a role should not be limited to moral support, but include concrete steps to provide financial support to the Ukrainian economy,” the diplomat said.
After a six-month break, Russia resumed gas sales to Kiev on December 9 under the so-called winter package, stipulating that Ukraine repays $3.1 billion of its $5.3 billion debt and pays for future supplies in advance.
Last Wednesday Russian energy giant Gazprom confirmed it had received the final tranche of Kiev's debt repayment.
The company’s spokesperson said, however, that the issue of further gas supplies to Ukraine remains unsettled as the Russian side has not received any advance payments yet.
