Marc Franco said the European Commission was satisfied that the talks would resume, with December 2 set as a preliminary date.
He said a special working group would convene by the end of the week to discuss the details of resuming the talks.
Earlier in the month, French Foreign Minister Bernard Kouchner, whose country holds the EU presidency, said all but one of the EU's 27 members had supported the resumption of the talks.
Lithuania made it clear that it would continue to oppose a resumption of negotiations with Russia. However, the negotiations do not require the support of all 27 member states.
Poland had also opposed negotiations on the new Russia-EU agreement, set to cover political, economic and trade relations, but has now lifted its objections.
Franco also said that President of the European Commission Jose Manuel Barroso had accepted an invitation from Russian Prime Minister Vladimir Putin for European commissioners to visit Moscow in the second half of January next year.
The EU announced on September 1 that it had suspended talks on the pact with Russia due to the presence of Russian troops in Georgia more than two weeks after the end of a brief war with the South Caucasus state over breakaway South Ossetia. The EU said it would not resume the talks until Russia pulled all its troops in Georgia back to their pre-conflict positions.
Although Moscow completed its troop pullout from buffer zones in Georgia in October, questions remain over the scale of its military presence in South Ossetia and Abkhazia, another disputed province. Russia recognized the independence of both republics at the end of August.
The new EU-Russia agreement is set to replace the 1997 Partnership and Cooperation Agreement, which was extended for a year when it expired in December 2007. The first round of talks on the new deal was delayed until July due to Polish and Lithuanian opposition.
