European Union-brokered talks between Ukraine and Russia about long-term gas supplies have been postponed.
The meeting was scheduled for April 14 in Berlin but the European Commission (EC) announced in a statement on April 10 that the meeting would be changed to a later date.
The EU already helped mediate a deal between Ukraine and Russia that helped ensure Ukraine and the European Union received Russian gas through the winter.
The EC statement said the trilateral meeting was still expected to take place before April 17.
Russian-Ukrainian relations have been rocky since Russia illegally annexed Ukraine's Crimean Peninsula last year and due to Moscow's continued support for pro-Russian separatists in eastern Ukraine.
Russia threatened last autumn to suspend gas supplies to Ukraine citing Kyiv's multibillion-dollar debt.
The EU stepped in to prevent a cut-off of supplies to Europe.
Some 40 percent of Russian gas imports to Europe pass through Ukrainian territory.
