Translated into Persian by Hamidreza Azimi, the book is the author's attempt to discuss secrets of success in an anxiety-free atmosphere to achieve personal and professional goals, ISNA wrote.
Alexander A. Gorjinia, said the goal of his book is to bring Iranian and German people closer.
"I believe that through various means, particularity arts and culture, one can go through the closed doors and reach inside the human's psyche," he added.
"There are many people out of Iran who intend to make economic success for Iran, but some countries prevent them in many ways like imposing sanctions," said Gorjinia in a speech at the ceremony.
He added, "But, I believe that the obstacles can easily be overcome, especially with the help of culture and art.
"All strangers are friends who have not been known to us. We can make a better atmosphere by our own behavior."
Head of the Research Institute of Cultural Heritage and Tourism (RICHT), Mohammad Beheshti, also in a speech, said, "Iranian culture and art are among the richest of their kinds and have made great achievements."
Gorjinia (born 1969 in Tehran) is a German businessman with Persian roots. He is an economic policy consultant and describes himself as an 'Iran expert'.
