Eneko Landaburu, head of the commission's Directorate General for External Relations, said the decision to hold the international conference was made at the September 1 European Union summit.
EU leaders decided at the summit to allocate around 500 million euros ($715 million) between 2008 and 2010 for the restoration of Georgia following its brief armed conflict with Russia, and in support of the country's economy.
Russia launched a five-day operation to "force Georgia to accept peace" after Tbilisi attacked South Ossetia on August 8 in an attempt to regain control over the republic, which split from Georgia in the early 1990s.
Landaburu said the Georgia donors' conference will be held at the level of ministers, and will be organized by the European Commission with the support of France, which holds the EU rotating presidency, and the World Bank.
Russia's response to the Georgian attack was condemned as disproportionate by a number of Western powers. On August 26, Russia drew further criticism when it recognized South Ossetia and Abkhazia, another breakaway Georgian republic, as independent states. So far, only Nicaragua has followed suit.
