On Sunday, the Iranian foreign minister visited China and after his meeting with Lavrov he headed to Brussels to meet the EU High Representative for Foreign Affairs and Security Policy Federica Mogherini, and the foreign ministers of Germany, France and the United Kingdom.
The French finance minister said he pushed U.S. Treasury Secretary Mnuchin this week for three things: exemptions for French companies operating in Iran; or the application of a so-called grandfather clause for deals struck in Iran since 2015; or an extension of the 90-day period to wind down operations in Iran.
The Iranian Foreign Minister is expected today in Brussels, the final stage of a diplomatic tour promoted in response to US President Donald Trump's decision to end the nuclear agreement (JCPOA) signed in 2015.
President Donald Trump's long-anticipated decision to pull the US out of the Iran nuclear deal and reimpose sanctions on the Islamic Republic will have a swift effect on some big companies.
After long negotiations, Iran agreed in July 2015 to freeze its nuclear program in return for the repeal of punishing worldwide sanctions.
The Iranian foreign minister is also set to hold talks with Russian head of foreign affairs Sergei Lavrov in Moscow on Monday and foreign chiefs from the United Kingdom, France and Germany, as well as Federica Mogherini, High Representative of the European Union for Foreign Affairs and Security Policy, in Brussels on Tuesday. "We will all save it together". "The answer is no", Mr Le Maire told reporters.
"Our meeting with Mrs Mogherini was good and constructive". Whatever decided should preserve and guarantee Iran's rights. "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". It also points to a refusal to accept that Mr Trump's decision on Iran, fulfilling a campaign pledge to U.S. voters, should be allowed to upend a global agreement negotiated over years and which worldwide observers say is working.
The EU, which along with Germany, France, Britain, Russia, China and the United States, signed the nuclear accord with Iran, does have some steps it can take to shield European business in Iran. In a separate interview on CNN's "State of the Union, " he said Iran's economic condition is "really quite shaky, " so the impact of sanctions "could be dramatic".
Europe, he added, must have an "independent financial tool" that would "allow our companies to trade freely in places Europe decided it was necessary or useful to do trade".
White House national security adviser John Bolton said Sunday that "it's possible" there will be secondary sanctions imposed on European companies as a result of the US withdrawal from the Iran nuclear deal. "We will try to uphold our side of the bargain".
She added that she will brief leaders of EU members states on Wednesday in Sofia, Bulgaria, which is about to host the EU-Western Balkan summit.
"We hope recent events will lead us not to trust in the West and even Europeans", he said Sunday, according to the conservative-linked Fars news agency.
"We'll outline what we might be able to do to keep trade flowing, but we'll tell them (Iran) that they should be under no illusion about our ability to influence American policy and to influence the economic situation." the diplomat said.
Pompeo said he was "hopeful in the days and weeks ahead we can come up with a deal that really works, that really protects the world from Iranian bad behaviour, not just their nuclear program, but their missiles and their malign behaviour as well".
In spite of the U.S. exit, Britain and Iran on Sunday expressed their commitment to ensuring that the accord is upheld, according to a statement released by British Prime Minister Theresa May's office.
"The extent to which we can keep this deal alive ... is something we need to discuss with Iran", said Ms Merkel, who earlier spoke with Russian President Vladimir Putin on the issue.
But European diplomats in Tehran fumed that Washington's withdrawal could undermine years of patient work to restore commercial and diplomatic ties with the Islamic Republic. "We don't have much to threaten the Americans".
