sanctions against Iranian oil sales. "They don't understand the meaning of this statement, because it is nonsense that Iran's oil is not (allowed to be) exported, while the region's oil is exported", the president's official website quoted him as saying.
In this debate, we will look at the state of the JCPOA what the European Union has to do to please Iran, and the tensions between the U.S. and Iran.
In May, Trump pulled out of a multinational deal under which sanctions on Iran were lifted in return for curbs to its nuclear programme, verified by the International Atomic Energy Agency (IAEA).
Since Trump's announcement of the USA withdrawal in May, his administration has sought to reimpose sanctions on Iran and has encouraged other countries to do the same.
Rouhani's European trip will be of "prime importance" as it could "provide a more precise picture of cooperation between Iran and Europe", the Iranian foreign ministry spokesman said at the weekend.
And the move to take Iranian barrels off the market isn't the only thing that could send oil prices higher: Venezuelan oil production continues to decline, and Libya's ability to sustain even limited oil exports is in question given political turmoil in the country.
The case cast a shadow over Iranian President Hassan Rouhani's visit to Austria on Wednesday at which both sides discussed issues including salvaging the Iran nuclear deal after the US decision to withdraw and reinstate sanctions on Tehran.
The other parties to the agreement say they remain committed to the deal so long as Iran is honoring it. Tehran said its foreign minister would meet counterparts from USA allies Britain, France and Germany, as well as Russian Federation and China, in Vienna on Friday to discuss ways of maintaining the nuclear deal. This US government will not stay in office forever.
But many believe nations will have to sever ties once Washington reimposes sanctions - to avoid losing access to USA markets and financing.
According to the sources, External Affairs Minister Sushma Swaraj had not given any assurance to her Iranian counterpart Mohammad Javad Zarif about oil import from Iran when they held talks here in May.
"But this must be balanced and if signatories other than the USA can guarantee Iran's interests, Iran will stay in the deal without the US", he added. "We don't keep it [to] ourselves", he said.
Iran had struck the JCPoA (Joint Comprehensive Plan of Action) deal with the USA, the UK, Russia, China, France and Germany after years of negotiations. "You made our dear Leader, the great nation of the Islamic Iran, and the world's Muslims proud by making such valuable and strong statements", he added.
The EU's foreign service, the EEAS, was not immediately available for comment on the meeting.
Foreign ministers from the remaining signatories to the 2015 nuclear deal - Iran, France, Britain, Germany, Russia and China - meet in Vienna on Friday to discuss salvaging the accord.
But so far it has proven hard to offset the impact of continued USA sanctions, with European firms reluctant to risk far-reaching US financial penalties to do business in Iran.
"These three countries account for about half of Iran's oil exports", it said.
