In a statement on Wednesday, Foreign Ministry Spokesman Abbas Mousavi congratulated the Mauritanian nation and government for holding the presidential election successfully.
He also offered congratulations on the election of Ghazouani as Mauritania’s new president.
Mousavi expressed hope that bilateral relations between Tehran and Nouakchott would grow further during the new president’s tenure.
Mauritania’s ruling party candidate Ghazouani won the election this week with 52 percent of the vote.
Ghazouani’s nearest rival, Biram Dah Abeid, came second with 18.58 percent.
Some 1.5 million people were eligible to vote on Saturday in Mauritania, a country of fewer than five million people covered largely by the Western Sahara Desert.
