"We were very clear we can't give guarantees but we can create the necessary conditions for the Iranians to keep benefiting from the sanctions-lifting under the JCPOA (the nuclear deal) and to protect our interests and continue to develop legitimate business with Iran", the European Union official said. The official said that Iranian hard-line factions that always opposed the nuclear deal are now pushing for a broader reevaluation of Iran's approach to nuclear issues.
The lead Iranian nuclear negotiator, deputy foreign minister Abbas Araghchi, said after Friday's talks that "the achievement was a united position by all participants" to try to save the deal.
He added that world powers must leave the door open for talks.

"There's little to no appetite in European capitals for the type of economic sanctions the U.S.is bringing back", Ellie Geranmayeh, a senior fellow at the European Council on Foreign Relations, said in a telephone interview.
"We expect the package to be given to us by the end of May", the official told reporters before talks in Vienna with Britain, China, France, Germany and Russian Federation. "The Plan B has just started to be figured out", Reuters quoted the official as saying.
The Iranian diplomat added, the Islamic Republic needs a guarantee it will be able to continue to sell its oil on world markets, have worldwide banking access and broad trade protections.
The IAEA, however, is "encouraging (Iran) to go above and beyond the requirements" of the deal in order to boost confidence, said a senior diplomat in Vienna, where the IAEA is based.
Iran's supreme leader set out a series of conditions on Wednesday for Iran to stay in the deal.
He said Iran was looking for "specific mechanisms and practical solutions" to convince companies to continue doing business with them.
In his first major foreign policy address since moving to the State Department from the CIA, Secretary of State Mike Pompeo said Washington would increase the financial pressure on Iran by imposing the "strongest sanctions in history" on the Islamic Republic if Tehran refused to change the course of its foreign and domestic policy.
The official said that if they were unhappy with how things panned out they would seek a ministerial meeting and then decide.
Trump denounced the accord, completed under his predecessor Barack Obama, partly because it did not cover Iran's ballistic missile development programme, its role in Middle East conflicts or what happens after the deal begins to expire in 2025.
The U.N. nuclear watchdog, which polices the pact, says Iran continues to comply with its terms.
The sweeping demands are likely to be rejected by Britain, France and Germany - diminishing the already narrow hopes of saving of the 2015 nuclear agreement.
