In an interview with the Kommersant business daily, Bernard Kouchner said the investigation, which is being set up, would involve a small group of politicians, lawyers and intellectuals. "A woman from Switzerland has been appointed the chair of the commission," he said.
Russia and Georgia fought a brief war in August after Georgia launched a military offensive against South Ossetia in an attempt to regain control over the republic, which split from Georgia in the early 1990s.
The French politician also said Russia and Georgia would have to declassify their archives on the August war, which left over 1,500 South Ossetian residents dead, or face international criticism.
The first round of international talks on the Georgian conflict in Geneva earlier this month was suspended until November, due to concerns over the status of South Ossetia and Abkhazia, recognized by Russia as independent states.
Kouchner has confirmed that Georgia's breakaway regions of South Ossetia and Abkhazia would take part in the November meeting. Russian President Dmitry Medvedev had earlier urged the participation of both republics saying that they should take part in the talks "as this directly concerns them."
