French Foreign Minister Laurent Fabius is set to hold a meeting with his Iranian counterpart Mohammad Javad Zarif in Paris.
Zarif, who has finished three rounds of nuclear talks with his American counterpart, John Kerry, in Geneva, will meet Fabius on Friday.
A surprise third round was added to the pre-planned two rounds.
US State Department officials said earlier that Kerry and Zarif held “substantive” talks in the Swiss city.
The Iranian foreign minister will also visit Berlin on Thursday to meet with his German counterpart Frank Walter Steinmeier.
A meeting is then slated to be held with European Union foreign policy chief Federica Mogherini in Brussels, the EU’s de facto capital.
Nuclear negotiators from Iran and P5+1– Russia, China, France, Britain, the US and Germany – wrapped up their latest round of talks on Tehran’s nuclear issue in Geneva on December 17, 2014.
The Geneva discussions were held almost three weeks after Tehran and the six countries failed to reach a final agreement by a November 24 deadline despite making some progress.
The two sides agreed to extend their discussions for seven more months until July 1, 2015.
They also agreed that the interim deal they had signed in Geneva in November 2013 should remain in place during the negotiations.
