German Economy Minister Sigmar Gabriel flew to Iran Sunday as the first top Western official to visit the country since world powers and Tehran reached a historic nuclear deal.

The Iranian nuclear deal has paved the way for the normalization of economic ties with Iran, said German Vice-Chancellor in Berlin prior to his departure to Tehran.

Gabriel who is accompanied by a high-ranking business delegation added that his three-day trip to Iran is aimed at deepening economic relations between Berlin and Tehran, provided the Iran nuclear agreement will be fully implemented.

Meanwhile, Germany's DIHK chambers of industry and trade welcomed Gabriel's Iran trip as 'an encouraging signal.'

The Iran nuclear accord is not only a significant political but also economic turning point, DIHK President Eric Schweitzer told German Press Agency, DPA.

The DIHK hopes reportedly to break the 10-billion euro export mark in Iran over the next four years as a consequence of the Iran nuclear agreement.

'In the next two years, exports could more than double the German exports to Iran to reach almost five billion Euros,' said DIHK chief foreign trade expert Volker Treier.

German companies are aiming for a lucrative multi-billion euro business deals in Iran after a historic nuclear accord was reached in Vienna on Tuesday, bringing an end to the 12-year nuclear row.
