He said that a large number of Afghan migrants have now returned to their homeland and are now active in their fields of study, IRNA wrote.
Many Afghan migrants, who studied at Iranian universities, are now teaching at different Afghan universities, Rezvani said.
Iran has provided an equal chance for Afghan migrants living in Iran to study at Iranian schools and universities, it still seems we have not gone far enough.
Although it is useful but more has to be done yet, he said, emphasizing the need for further efforts by Iran and Afghanistan to introduce a scientific and cultural diplomacy between the two countries.
Iran and Afghanistan need cultural and scientific diplomacy to develop ties to the level the two neighboring countries with longstanding amity deserve.
Afghanistan has been grappling with civil war and foreign invasion over the recent decades. The instability and unrest in Afghanistan has significantly affected the scientific and cultural output of the country, which requires further cooperation between Iran and Afghanistan as two neighbors with common civilization and cultural affinities.
Iran and Afghanistan signed a cultural agreement in 2016 based on which they were expected to open their own cultural centers in Tehran and Kabul. The agreement, however, still remains on paper after years.
