Medvedev, speaking at the World Economic Forum in Davos, Switzerland, said efforts to advance a customs union with former Soviet republics didn't equate to an about-face on Kremlin policy.
"This is complete nonsense and there is no path back into the past," he was quoted by state-run news agency RIA Novosti as saying. "We have all (former Soviet republics) become different and are looking into the future and we have a clear-cut plan for strengthening cooperation on a mutually advantageous basis."
Russian Ambassador to NATO Alexander Grushko reacted angrily to statements by U.S. Secretary of State Hillary Clinton last month. Clinton said following a human rights meeting in Ireland that Russian efforts to create a Eurasian trade block was tantamount to a move to "re-Sovietize" Eastern Europe and Central Asia.
Grushko said such sentiments were "absolutely incongruous" with Moscow's economic policies.
