Addressing media representatives in Vienna on Thursday, Fabius said we have not reached yet the end of the nuclear negotiations.
'We want to make further progress in the talks towards a finalized deal which would hopefully be a lasting accord,' he added.
Fabius stressed again Paris was aiming for what he called 'a robust agreement'.
'We are saying 'yes' to a civilian nuclear program but 'no' to a military nuclear program,' the French minister said.
France is widely viewed as the most hardline member among the six world powers (the US, Russia, China, Britain, France and Germany) which are negotiating a potentially historic nuclear deal with Iran.
