Russian gas giant Gazprom said it would double prices for Georgia in 2007.
Georgia will be charged $230 per 1,000 cubic metres of the fuel next year, up from this year's 110 dollars, Russian news agency Interfax reported.
But with Moscow in the thick of an anti-Georgian campaign, the deal is likely to renew concerns the Kremlin uses the world's largest natural gas company to enforce its diplomacy.
'There is more politics than economics in the price,' Georgian Foreign Minister Gela Bezhuashvili said Thursday on Moscow radio station Ekho Moskvy.
Tbilisi is officially withholding comment until contracts are signed and the price finalized, Georgian parliament and cabinet officials told Russian news agencies.
