TEHRAN, Aug. 25 (Xinhua) -- Iran's Foreign Minister Mohammad Javad Zarif said Saturday that the Tehran is still waiting for Europe's guarantees on the sale of Iranian oil and banking relations, Press TV reported.

"The European Union was supposed to carry out some measures, including the preservation of the sale of Iranian oil and banking channels, which we are still waiting (for Europe) to do," Zarif was quoted as saying.

Zarif made the remarks on the sidelines of a conference on Iran's political development after U.S. unilateral move to pull out of a 2015 historic nuclear agreement.

Iran's has incessantly urged the European signatories to the 2015 nuclear deal to take "practical and tangible measures" to protect Iranian interests after the U.S. pullout.

Iran signed the landmark nuclear deal with the United States, Britain, France, Russia and China plus Germany in July 2015 to halt its nuclear weapons program in exchange for sanctions relief.

U.S. President Donald Trump decided on May 8 to quit the Iranian nuclear deal and vowed to reimpose sanctions, including oil embargo, on Tehran.

Iran is currently in talks with France, Britain and Germany to revive the "blocking statute," a 1996 regulation that prohibits European Union companies and courts from complying with foreign sanctions laws.
