"At present, improving banking cooperation between the two countries and removing hurdles in financial and banking matters are necessary and vital to develop economic and trade ties," Gholamhossein Shafiei was also quoted as saying by the official news website of ICCIMA.
Improving banking ties, he added, must be put on the agenda of both governments.
The official was speaking at an Iran-Sweden trade meeting, attended by Swedish Minister for European Union Affairs and Trade Ann Linde and the head of Sweden Trade Council, Ilva Berry.
According to Financial Tribune, the Swedish officials were in Tehran on Saturday as part of a high-ranking political and economic delegation led by Swedish Premier Stefan Lofven on a three-day visit.
Lofven met with President Hassan Rouhani in a separate meeting, in which the president said the European Union should buttress the bloc's banking relations with Iran so as to optimize the opportunities provided by the 2015 nuclear accord.
The Iranian president also said the country favors better banking transactions with Sweden.
In his meeting with the Swedish economic delegation, Shafiei spoke of the potential of bilateral cooperation in various sectors such as infrastructure, auto manufacturing, energy, environment, food and agriculture and mining among others.
The fast growth of trade deals between the two countries during the past year and a half, decrease in the risk of trading with Iran by the Export Guarantee Fund of Sweden and opening of a Swedish trade office in Tehran "must be looked upon as a sign of the beginning of serious collaborations between Swedish and Iranian companies", he said.
Shafiei noted that the healthy level of past cooperation can therefore be revived, by focusing on "attracting investments and transferring knowhow and technology".
