"Bilateral discussions between France and Iran will take place on Wednesday," Fabius said yesterday at a news conference in Algiers after Iranian and US delegations began two days of direct negotiations in Geneva.
"After these discussions, there will also be discussions between the Iranians and the Russians. There may be others. Anyway, the three (countries) that I know about are the Americans, the Russians and the French," he added.
"The Americans gave us notice about these talks and we also said we would have talks with the Iranians.
Senior Iranian and US officials held what Tehran's top negotiator dubbed "constructive" talks yesterday, as Washington warned tough choices were needed for a lasting accord on Tehran's controversial nuclear programme by a July 20 deadline.
The closed-door meeting in Geneva marks a new effort to find common ground between Tehran and Washington, amid concerns that tensions between the two could damage efforts to strike deal between the Islamic republic and world powers.
