"Once again, the great Iranian nation has witnessed the success of the ambassadors of Iranian art in international art community in conveying to the world the voice of the noble Iranian people, which is the voice of culture, civilization, peace and national dignity and pride," Bahram Qassemi said, reported Press TV.
He added that artists shoulder a great responsibility to strengthen friendship and unity among nations at the current juncture.
It is very pleasing to see the proficient and diligent Iranian director once again managed to deliver the Iranian nation's message of peace and friendship to the entire world through art, the spokesperson said.
'The Salesman' won the Oscars on Sunday for best foreign-language film. However, Farhadi had boycotted the gala over US President Donald Trump's executive order banning arrivals into the US from seven Muslim countries.
The award was accepted by two prominent Iranian-Americans representing the Iranian director. Anousheh Ansari, famed for being the first female space tourist, and Firouz Naderi, a former director of Solar Systems Exploration at NASA.
Qassemi also hailed the 'courageous' decision by Farhadi and the movie's lead actress, Taraneh Alidoosti, to boycott the Oscars ceremony "out of respect for the wise people of Iran and six other countries who were disrespected by the political and inhuman travel ban order".
It showed that the voice of moderation and peace-seeking continues to reverberate throughout the world despite the conduct of all extremists and unilateralists, the spokesman underlined.
Managing Director of the Farabi Cinema Foundation (FCF) Ali Tabesh in a message congratulated Oscar-winning Director Asghar Farhadi for winning the Oscar award.
Tabesh described the distinguished moviemaker as a 'bright star' in the field of art.
Speaking while receiving the award, Ansari read a message on behalf of film's director.
"My absence is out of respect for the people of my country and those of other six nations who have been disrespected by the inhumane law that bans entry of immigrants to the US," the space tourist said. "Dividing the world into the 'us' and 'our enemies' categories creates fear, a deceitful justification for aggression and war."
The Oscar-winning Iranian filmmaker announced in January that he had decided not to participate in the Oscars ceremony to protest the US president's executive order.
Trump's executive order, issued on January 27, blocked entry into the United States for 90 days for citizens from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen. It also suspended entry of all refugees for 120 days and barred Syrian refugees indefinitely.
US District Judge James Robart in Seattle, Washington, suspended the order nationwide on February 4 after his state challenged its legality. A three-judge panel in the 9th US Circuit Court of Appeals upheld Robart's ruling.
The White House has vowed to issue a revised travel ban which would still target the same seven Muslim countries.
Farhadi's decision came after the Iranian actress Alidoosti said on January 26 that she had made up her mind to boycott this year's Academy Awards ceremony in a show of protest against the US president's decision to impose visa bans on Iranians.
