The summit, being held Monday in Brussels, is meant to allow European leaders to express their outrage over Russia's conflict with Georgia and condemn its unilateral recognition of the breakaway republics of South Ossetia and Abkhazia. But because of Europe's heavy dependence on Russian oil and natural gas, punitive actions are unlikely, The Daily Telegraph reported.

The leaders are divided between British Prime Minister Gordon Brown, who has vowed a "root and branch" review of his country's relations with the Kremlin, and French President Nicolas Sarkozy, who, the newspaper said, seems eager to sooth the situation and avoid jeopardizing ties with Russia.

Russian President Dmitry Medvedev said before the Brussels summit that there was "no turning back" from Russia's recognition of Georgian republics, saying, "We have taken our decision and we took it irrevocably."

Meanwhile, tens of thousands of demonstrators were expected to rally across Georgia and in other European cities, calling on the EU members to punish Russia, the British newspaper said.
