Russian President Dmitry Medvedev said today there was no deal to end a row crippling gas supplies to eastern Europe, but pledged that talks would go on.
"Unfortunately, and I would like to underline this, all the efforts have so far yielded no results," Mr Medvedev said as he opened a Kremlin meeting of nations affected by the dispute.
In Brussels, the Czech presidency of the European Union said it was not satisfied by gas talks in Moscow and urged both sides to reach a deal as negotiations continued into Saturday evening.
"We expected both parties to announce that they had reached an agreement on the resumption of Russian gas supply to the EU via Ukraine. This was not the case," Czech Industry and Trade Minister Martin Riman said in the statement.
The lack of gas has closed factories across eastern Europe. It has also raised questions about Russia's reliability as an energy supplier and Kiev's fitness as a partner for the EU.
Russia cut off supplies to Ukraine on Jan. 1 because it would not pay higher prices. Six days later export flows to eastern Europe through Ukraine ceased amid Russian accusations that Kiev was "stealing" gas intended for export.
Kiev says it cannot afford such high prices and wants Russia to pay higher transit fees for gas it exports through Ukraine.
Earlier in the day, Russian Prime Minister Vladimir Putin did not hold planned negotiations on the crisis with his Ukrainian counterpart, Ms Yulia Tymoshenko.
There was no official explanation but a source close to the Russian side said it appeared Tymoshenko lacked the necessary mandate to discuss a solution and had come to Moscow "empty-handed".
Ms Tymoshenko clashed with her domestic political rival, President Viktor Yushchenko, on the eve of her trip to Moscow about tactics for solving the dispute.
In Kiev, a source in Mr Yushchenko's office said there were no divergences in position between the president and the prime minister, who had complete authority to negotiate. "The prime minister has a full mandate at the talks. Otherwise, she would not be taking part in them," the source said.
Russian gas giant Gazprom said it was determined to reach an agreement today and would make every effort to do so.
The row has angered the European Union, which gets about a fifth of its gas from pipelines that cross Ukraine, and left many countries in eastern and southern Europe with no supplies in the depths of winter.
A spokesman for European Union Energy Commissioner Andris Piebalgs, who attended the Moscow summit, described the discussions as "constructive".
"The commission is encouraged by these discussions, which will continue," he said. "Hopefully we will have results and those results cannot be different than the immediate resumption of gas flows to Europe."
Gazprom says Ukraine should pay European-level prices of $450 per 1,000 cubic metres (tcm) of gas for 2009, up from $179.5 per tcm in 2008. But Ukraine, heading into its worst recession for a decade, has said it can afford only $201.
Ms Tymoshenko, a former gas trader, said on Friday there should be no intermediaries in the gas trade between Russia and Ukraine and ruled out any sell-off of Ukraine's pipelines.
The row has focused minds in Europe about the need to find new routes for gas but experts say any solution would take years to build and Gazprom says EU dependency on Russian gas is forecast to increase over the coming years.
