Russia earlier cited "a lack of directives and authority" on behalf of the Belarusian delegation which led to the failure of the talks to reach an agreement for customs-free oil deliveries to Belarus for domestic use in 2010.
It would release Belarus from paying customs taxes on the 5-6 million tons of oil it uses domestically for the year.
"The negotiations were carried out on a daily basis from December 10. Unfortunately, we have failed to sign the relevant agreements," the press service said in a statement.
Earlier this week, Russian Deputy Prime Minister Igor Sechin said the agreement could be signed in Moscow on December 30-31. He said that if the agreement was not signed by then, Belarus would be obliged to pay 100% of the customs duties for oil deliveries.
The press service said on Thursday that the Russian government was ready to resume customs-free deliveries as soon as the relevant documents had been signed.
Belarusian officials have been invited to continue the stalled negotiations in January in Moscow.
