French President Emmanuel Macron is cautiously hopeful for a breakthrough in the US-Iran relations and is seeking to bring the two together
Tehran and Washington have been at loggerheads since May last year when Trump abandoned a 2015 nuclear deal and began reimposing sanctions on Iran in a campaign of "maximum pressure."
Following the Group of Seven summit in France in August, though, Trump spoke openly of his willingness to meet his Iranian counterpart face-to-face, if the conditions were right.
Diplomats hope a meeting would help de-escalate tensions in the Gulf that have flared since May when the US ended all waivers in its unilateral sanctions that seek to stop Iran from selling any oil.
Iran has responded by reducing its commitments under the nuclear deal and Trump has deployed military assets to the region.
Macron also met German Chancellor Angela Merkel and British Prime Minister Boris Johnson on Monday afternoon where they agreed with the US that Iran was responsible for the blasts at the Abqaiq and Khurais facilities.
"There is no other plausible explanation," the leaders said in a joint statement.
But the three European countries, which remain part of the nuclear deal negotiated under former US president Barack Obama and are trying to salvage it said the solution was diplomacy.
"We urge Iran to engage in such a dialogue and refrain from further provocation and escalation," they said.
