Hashemi said the current mood in Iran "is anything but optimistic", adding people are angry that despite Iran's "good faith" in complying with the deal, Trump's policies dashed those hopes "and highlighted U.S. antagonism towards Iranians". A total of $100bn in frozen Iranian assets was also released.
Iran may pull out of its nuclear deal with global powers if Western banks continue to refuse doing business with the country over fear of American sanctions, Tehran's deputy foreign minister has warned. In his speech at the London think tank, Araqchi said they will withdraw from the deal if it doesn't begin to see some concrete economic benefits.
But will Iran pull the trigger and leave the JCPOA?
According to the New York Post, the Islamic Republic's Deputy Foreign Minister announced the possibility during an global conference in London, saying the UK, China, France, Germany, Russia, and the United States' sanctions against Iran have caused big banks to stay away from major business deals.
However, the future of the hard-won agreement between Iran and the five permanent members of the UN Security Council plus Germany is highly uncertain.
According to United Nations inspectors, Iran continues to be in compliance with that condition. Conservatives, however, opposed the agreement saying the U.S. is not a trustworthy partner.
Up until now, Iran had indicated that it would stick with the deal if the European partners did the same.
Iran has raised that prospect in public statements before.
Instead, they have found that banks are hesitant to do business with them.

This figure is still below the quota of Saudi Arabia at 10.058 million barrels per day. And the IEA continues to beat the same drum.
However, there are several United States sanctions that remain in place.
"If the same policy of confusion and uncertainties about the JCPOA (Joint Comprehensive Plan of Action) continues, if companies and banks are not working with Iran, we can not remain in a deal that has no benefit for us. That's a fact", Araqchi said.
A wave of protests in recent months, widely blamed on the country's economic woes and years of political tension and alleged corruption, have added more pressure on the administration of reformist President Hassan Rouhani to do something about the economy. President Trump claims the Iranian government has received a "windfall" of $100 billion, $1.8 billion of which was received in cash. In 2016, President Hassan Rouhani ordered the start of planning on the development of nuclear marine propulsion in reaction to what he called US violations of the nuclear deal. For one, he believes the nuclear deal fails to cement a solution to Iran's ballistic missile program. Araghchi also said that such comments represent a violation of the terms agreed in 2015.
"The deal would not survive this way even if the ultimatum is passed and waivers are extended", said Iran's lead nuclear negotiator, referring to President Trump's recent decision to issue a "waiver" that extended the Iranian nuclear agreement. Trump has a May 12 deadline to issue fresh waivers.
"First, it must demand that Iran allow immediate inspections at all sites requested by worldwide inspectors".
"The Iranians might do things that have nothing to do with nuclear weapons but advance the technical aspects of their nuclear programs over a long period of time", said Marashi. My policy is to deny Iran all paths to a nuclear weapon-not just for ten years, but forever...
Iran has dismissed the U.S. calls for halting its missile programme development, saying it is only for deterrent purposes.
In an about-face, Iran on Thursday indicated that it is willing to walk away from the 2015 nuclear deal if major banks continue to stay away from doing business with Iran, for fear of violating US sanctions that remain in place.
If the deal-officially known as the Joint Comprehensive Plan of Action (JCPOA)-was to collapse, Araghchi said, the world would face "another nuclear crisis".
