Iran's Deputy Foreign Minister for Political Affairs Abbas Araqchi said Germany, France and the United Kingdom had 60 days to provide Iran *with enough guarantees to ensure it could* stay in the deal, according to IRNA.
So Trump's decision to reinstate Iran sanctions might not be as big a deal as one would think.
U.S. President Donald Trump said on Tuesday the United States was exiting an worldwide nuclear deal with Iran and would impose new sanctions that seek to reduce oil exports from OPEC's third-largest producer.
Bolton said he was not present when the aide, Kelly Sadler, told other communications aides at a closed-door staff meeting that McCain's opposition to Gina Haspel as Central Intelligence Agency director did not matter because "he's dying anyway".
Iran's President Hassan Rouhani said he wanted to negotiate with the Europeans, Russia and China on terms for continuing the deal, but the door was now open to resume the nuclear programme.
Trump said that he will re-impose even stronger sanctions against Tehran to make the Islamic republic sit at the negotiation table for changes of "flaws" in the deal.
Mogherini said "expert talks" on relevant financial and economic issues such as banking transactions and oil would begin soon and the deputy foreign ministers from the three European nations and Iran would meet in Vienna next week.
"We hope that with this visit to China and other countries we will be able to construct a clear future design for the comprehensive agreement", Zarif said, speaking alongside his Chinese counterpart, Wang Yi.
"We should not exaggerate the influence of Iran on oil price. A lot depends on what we can do within the next few weeks".
Tehran has warned it is preparing to resume "industrial-scale" uranium enrichment "without any restrictions" unless Europe can provide solid guarantees that it can maintain the economic benefits it gained from the nuclear agreement despite the United States reimposing sanctions. "I think that will sink in and we'll see what happens then". She has reported extensively from the Middle East on the rise and fall of terrorist groups such as ISIS in Iraq.
That is part of a flurry of diplomatic activity following Trump's unilateral withdrawal from what he called "a terrible, one-sided deal", a move accompanied by the threat of penalties against any foreign firms doing business in Iran.
It also demanded that Iran cease supplying weapons to the Houthi rebels, who have been at war with Tehran's archenemy Saudi Arabia, end cyberattacks against the US and its allies, stop menacing USA military ships in the Persian Gulf and abandon its rhetoric about destroying Israel.
Another could be an independent financing mechanism allowing European companies to avoid US banks. The commission is expected to unveil them to European Union leaders at a summit in Sofia, Bulgaria, on Wednesday.
The U.S. says the sanctions will also sharply curtail sales of oil by Iran, which is now the world's fifth-largest oil producer.
For such companies, Iran's value lies more in its potential for growth - the country has been deprived of investment for years and has a young demographic.
"The snap-back of US sanctions will have a major effect on shipowners and their insurers and Skuld and the IG are closely monitoring developments", Skuld said on its website.
