The former Manchester United defender will lead the French national team into Euro 2012 this summer, but he has left his future open to speculation.
"My intention is to continue with the France team. I have not changed my mind," Blanc told Le Parisien.
"But the situation is that my contract has not yet been extended. And I'm not the kind of guy who will keep tapping at the door. If it's clear, it's clear.
"If an exceptional challenge is proposed to me, I can very well decide to leave the French team. But that is not the case at the moment."
France begin their Euro 2012 campaign against England on June 11.
