Lausanne: Hawkish French Foreign Minister Laurent Fabius arrived on Saturday at nuclear talks with Iran in Switzerland saying he wants to achieve a "robust" deal.
"I am coming here with the desire to move towards a robust agreement," Fabius told reporters in Lausanne. "We have made progress on certain issues but not enough on others."
He said he was "insisting" that any deal included mechanisms to ensure that the Islamic republic, which denies wanting nuclear weapons, complies with its commitments.
Fabius joined US Secretary of State John Kerry and their Iranian counterpart Mohammad Javad Zarif ahead of a Tuesday deadline to agree the contours of what they hope will be a historic agreement.
German Foreign Minister Frank Walter Steinmeier was due to join them later Saturday and hold a working lunch with Kerry and Fabius, US officials said.
China and Russia`s foreign ministers, the other two countries involved in the long-running talks, were reportedly expected on Sunday.
