Earlier in the day, Zarif said he was in Vienna "to listen to practical solutions, rather than slogans".
The pillars of the European Union's strategy are: European Investment Bank lending, a special measure to shield EU companies from U.S. secondary sanctions, and a Commission proposal that EU governments make direct money transfers to Iran's central bank to avoid United States penalties.
He gave a similar message in a call to German Chancellor Angela Merkel, the president's website reported. "It only included some general promises like previous European Union statements", Tasnim quoted Rohani as saying.
It also specifies the fuel Arak must use and says its spent fuel for the reactor's lifetime must be shipped out of Iran.
Besides, Commander of the IRGC Quds Force Qasem Soleimani on Tuesday lauded Rouhani for responding strongly to a USA plan aimed at blocking Iran's oil sales, saying "this is the Dr. Rouhani we used to know and the one he should be". European countries, as well as Russian Federation and China, all condemned Washington's move. "We are trying to do it (economic package) before sanctions are imposed at the start of August and then the next set of sanctions in November".
"We will not be able to compensate for everything that arises from companies pulling out of Iran", Heiko Maas told reporters before a round of talks among the remaining parties to the deal. "To save the deal, other signatories should compensate for USA sanctions", a senior Iranian official told Reuters on Friday.
"We've made some progress, including on safeguarding some crude (oil) sales, but it's unlikely to meet Iranian expectations".
The head of Iran's Revolutionary Guards said on Thursday their forces were ready to implement Iran's threat to block the Strait of Hormuz and that if Iran can not sell its oil under the US pressure, no other regional country will be allowed to.
This week, the European Parliament approved a key component of the package, giving the European Investment Bank authority to invest in Iran despite the USA sanctions. Further sanctions on oil and transactions with the central bank of Iran will come into effect November 6. "Enough with the policy of appeasement and weakness regarding Iran".
Also, the bank has expressed concerns that it will have difficulty raising money in financial markets if it defies the US sanctions.
They also vowed to maintain financial channels, promote export credit cover and air, sea and overland transport links, and to work for the "the protection of companies from the extraterritorial effects of USA sanctions".
Iran's economy is already suffering from the sanctions that Washington re-imposed after walking away from the nuclear agreement, and the US has threatened to punish companies from other nations that continue doing business with Iran.
In 2012, Iran threatened to block the strait in response to sanctions by the United States and the European Union against the country's nuclear program.
Since Trump's announcement, Iran's rial currency has fallen, prices have risen and the country has been hit by street protests and strikes.
