In a Thursday meeting with Saudi Arabia's crown prince in Riyadh, Macron repeatedly said that he wanted to keep the deal.
Macron, on his debut visit to the Middle East, flew in from a tour of the United Arab Emirates for his first face-to-face talks with Crown Prince Mohammed bin Salman, AFP reported.
US pressure to renegotiate the Iran nuclear deal could push Tehran into deciding to build its own nuclear weapons, Macron had told Time magazine in an interview published Thursday.
Tehran has always stressed that its nuclear activities were peaceful.
Last month, Trump broke ranks with European allies, Russia and China by refusing to re-certify Iran’s compliance with its nuclear deal with world powers.
The Republican president gave Congress 60 days to decide whether to re-impose economic sanctions on Iran, lifted under the pact in exchange for curbing its nuclear activities.
European leaders say they are determined to keep alive the accord which offered Iran an economic lifeline and opened new investment opportunities for European businesses.
