Djokovic returns to the Philippe Chatrier Court tonight
France sports minister Amelie Oudea-Castera has said Novak Djokovic's message about Kosovo "must not be repeated".
The Serb wrote "Kosovo is the heart of Serbia - stop the violence" on a camera lens, after his first round win at the French Open.
Amelie Oudea-Castera described it as "militant" and "very political".
The International Tennis Federation has not opened a disciplinary case.
Djokovic returns to the Philippe Chatrier Court tonight, to play Marton Fucsovics in the second round.
Carlos Alcaraz is also in action today - the top seed plays Taro Daniel.
