Speaking at the joint press conference in Paris, French President Emmanuel Macron said France will continue to work with the existing nuclear deal, which it considers as the best option available.
The French president also said he doesn't see how exiting the nuclear deal would help improve regional stability.
How can one "think that a total absence of controls and commitments is better than the 2015 framework?" Macron asked.
Macron also raised the issue of the Palestinian territories, expressing his "condemnation of any form of violence toward Palestinian civilians and in particular, these past few weeks in Gaza."
Germany, Britain, France, Russia and China, which also signed the Iran nuclear agreement, have said they want to preserve it.
Iran informed the U.N. nuclear watchdog on Tuesday that it will increase its nuclear enrichment capacity within the limits set by the 2015 nuclear agreement, the Joint Comprehensive Plan Of Action (JCPOA).
