An Iranian top official said on Sunday that the EU has pledged to take action before the U.S. ban on importing oil from Iran takes effect in November, Press TV reported.
The European countries have made this promise in an attempt to make up for the possible losses that Tehran may suffer, First Vice President Es'haq Jahangiri was quoted as saying.
The U.S. sanctions have so far not limited European countries in the economic sector, particularly with regard to oil purchases and trade, Jahangiri noted.
The impact has not been "very determining" despite the departure of some private companies, particularly the European ones, he added.
U.S. President Donald Trump signed an executive order Aug. 6 to reimpose the first round of sanctions on Iran, which had been lifted under the 2015 nuclear deal, to levy "maximum economic pressure" on the Islamic republic.
The sanctions will cover Iran's purchases of U.S. dollar, its trade in gold and precious metals, and its automotive sector.
The second round of embargo will be reimposed in early November with the aim of curtailing Iran's oil exports and shipping sectors.
