Behbahani said that a number of foreign banks, which had written letters to Iran that it would be impossible for them to continue cooperation due to sanctions, are now saying that they want to resume cooperation, Mehr News Agency reported.
He added that a major European bank has voiced its readiness to resume financial transactions with Iran after several sessions held between the two sides.
The US withdrew unilaterally from the nuclear deal in May and reimposed sanctions against Iran which had been lifted under the 2015 agreement. Washington’s sanctions have targeted several individuals and sectors in Iran including banking and oil sectors.
The other parties to the deal – Russia, Britain, China, France and Germany – did not approve the US pullout and remained committed to the previous accords.
Since then, Iran and the remaining parties to the deal have been holding negotiations to save the accord.
The European Union has frequently announced its strong determination to preserve the nuclear deal, irrespective of the decision by the US president.
