She said all sides had agreed to find practical solutions over the coming weeks.
"If you look at the advances that Iran has made under cover of this agreement, its conventional military and terrorist advances, in Iraq, in Syria, in Lebanon, in Yemen, since 2015, Iran was really on the march", Bolton told ABC´s "This Week". "We urge the United States to ensure that the structures of the Joint Comprehensive Plan of Action [JCPOA, as the deal is officially named] can remain intact", the statement said, "and to avoid taking action which obstructs its full implementation by all the other parties to the deal".
Lavrov told Zarif that all the remaining signatories of the JCPOA have "legitimate interests" in keeping the deal and that "therefore we need to defend the legitimate interests of each of us together". He has provided proximate proof that any deal the (US) makes, even a successful one, may be tossed aside on the whim of this or any other president.
The announcement by Donald Trump that the U.S. would pull out of the agreement came with the restoration of sanctions against Tehran, including six individuals and three companies it claims are funnelling millions of dollars to the Islamic Revolutionary Guard's elite Quds Force.
"We have to accept, be realistic about the electrified rail, the live wire of American extraterritoriality and how that can serve as a deterrent to businesses", Johnson said.
Iranian officials have threatened to resume enrichment.
President Barack Obama said the only alternative to the weak-kneed deal was war, and some Trump critics have said his abandonment of the deal could send Iran scurrying to get its nukes, something that would now take about a year as compared to maybe three months before the deal. "It would not stop Iran from getting nuclear weapons".

"We have started an intensive process (and) the economic benefits inside the JCPOA (Iran deal) should be preserved for Iran", Mohammad Javad Zarif said on arrival in Brussels ahead of a meeting with his British, French and German counterparts.
John Bolton, White house adviser on national security, does not exclude the application of sanctions against European companies that trade with Iran. They include retaliatory sanctions, allowing the European Investment Bank to invest directly in Iran and coordinating euro-denominated credit lines from European governments.
However, Washington's decision to pull out of the global nuclear deal and its threat to reimpose sanctions on firms doing business in Iran has cast fresh doubt over this new trade.
Trump's decision has angered Washington's allies in Europe as well as China and Russian Federation.
The European ministers also brought up in the talks their concerns over Iran's ballistic missile programme and regional activities, diplomats said.
But the fact is that the Iran deal was not meant to address Iran's policies in the region or its missile developments.
The bill is indicative of the increased pressure that President Hassan Rouhani's moderate administration is feeling from the hardliners to not compromise in the talks.
