BIARRITZ, France — A top Iranian official paid an unannounced visit Sunday to the G-7 summit and headed straight toward the heart of the city where leaders of the world's major democracies have been debating how to handle the country's nuclear ambitions.
France's surprise invitation of Iranian Foreign Minister Mohammad Javad Zarif was a high-stakes gamble for French President Emmanuel Macron, who is the host of the Group of Seven gathering in Biarritz.
Zarif spent about five hours in Biarritz after his plane touched down at the airport, which has been closed since Friday to all flights unrelated to the official G-7 delegations.
A senior French official, speaking on condition of anonymity to discuss the sensitive talks, said Macron personally informed U.S. President Donald Trump about the invitation to Zarif.
The official noted that Macron and Trump met for two hours Saturday and discussed Iran at length, as well as at the informal group dinner Saturday night.
Another French official said that France "is working in full transparency with the U.S. and in full transparency with European partners." The Iranian met with Macron as well as diplomats from France, Germany and Britain at the Biarritz city hall, the official said.
Zarif, who is under U.S. sanctions, had been scheduled to go to Asia as part of a tour to seek support for Iran amid the American campaign against it since Trump withdrew the U.S. from Tehran's 2015 nuclear deal.
U.S. Treasury Secretary Steve Mnuchin said Trump had not "set preconditions" on negotiations with Iran.
