Ali Akbar Velayati, a top adviser to Iran's Supreme Leader Ayatollah Ali Khamenei.
The Joint Comprehensive Plan of action, as the nuclear deal is officially known, was negotiated during the U.S. presidency of Barack Obama.
"An essential part of the agreement and its implementation regards Iran having the possibility of benefiting from the lifting of sanctions, and this is exactly why we are discussing tonight, operational concrete steps that we can put in place", Mogherini told reporters before the talks at the United Nations.
Speaking to reporters in Tehran on Tuesday, Ali Akbar Velayati, the Leader's advisor on worldwide affairs, said, "Trump's and Pompeo's dream will never come to reality and this is definitive".
Reports of the "ghost ships" come as President Trump and Iranian President Hassan Rouhani were both in NY for the annual United Nations gathering.
In a major setback to the United States and Trump's administration, the European Union has made a decision to constitute new ways to enable legal trade with Iran, despite USA sanctions, which are expected in November. "The case of North Korea is very different from that of Iran".

The United Kingdom, France, and Germany implored the Trump administration to stay in the Iran deal.
The US administration reintroduced the previous sanctions while imposing new ones on the Islamic Republic.
The sanctions on Iran's oil are now expected to remove more than 1 million bpd from the oil market, compared to earlier projections of around a 500,000-bpd loss, before the United States started to show signs that waivers would be given sparingly, if at all. It also introduced punitive measures - known as secondary sanctions - against third countries doing business with Iran.
Velayati further emphasized that Iran would never yield to the United States and its stooges.
The countries are still working on details of how future trade deals with Iran would work. "Maybe someday in the future".
"Naturally, if someone is keen on having a meeting and holding dialogue and creating progress in relationships, that person would not use the tool of sanctions and threats [and bring] to bear all of its power against another government and nation", Rouhani told NBC News.
Zangeneh said such a plan isn't possible long-term, though Washington seems determined to cut Iran's crude exports, "even if for just a month". "I am sure he is an absolutely lovely man", Trump wrote in a post on his official Twitter account.
