President Jacques Chirac met in Paris with a special envoy sent by Iran's president, Mahmoud Ahmadinejad, though no details of the talks were released.
Hashemi Samareh and Chirac discussed questions of regional importance during the Tuesday night meeting, Chirac's office said.
Chirac "reaffirmed France's support" for EU foreign policy chief Javier Solana, who has been leading European efforts to persuade Iran to suspend its nuclear activities, the presidential Elysee palace said in a statement.
Solana was to meet with Tehran's chief nuclear negotiator, Ali Larijani, on Thursday for a third round of talks aimed at getting Iran to freeze its nuclear program. The venue of the meeting remained uncertain, though Paris is a possibility.
