Russia's gas monopoly Gazprom has said it will more than double prices of gas supplies to Georgia from 2007.
Russia proposed to hike Georgia's gas bill after the two countries' foreign ministers were unable at talks yesterday to defuse a crisis in their relations.
Gazprom said it would charge Georgia's capital city Tbilisi $230 (£121) for 1,000 cubic metres of gas, compared with the $110 current cost.
Georgia's foreign minister is in Moscow for talks in an effort to defuse tensions between the two nations.
The ex-Soviet neighbours are bitterly divided over Tbilisi's drive to join NATO and the European Union, and over Georgian breakaway regions that are propped up by Moscow.
Russia stunned its European customers in January when it turned down the gas taps to Ukraine to press a demand for a price hike, disrupting transit supplies to Europe for the first time in four decades.
Georgia, led since 2004 by pro-Western President Mikhail Saakashvili, believes Russia is using gas as a weapon to bring the former Soviet state to heel.
Georgia's exports have been hit by a months-old Russian ban on exports of wine and mineral water, ostensibly on health and safety grounds. Government leaders say they expect the blockade to wipe 1.5% points of its economic growth this year.
