“I sincerely congratulate my brother Hakan Fidan on his appointment as Foreign Minister of the Republic of Turkey,” Amirabdollahian said in a post on Twitter.
“We have met and held talks on many occasions. He is a wise and professional diplomat,” he added.
Referring to the outgoing foreign minister of Turkey, Amirabdollahian said, “And God bless my brother Mevlut Cavusoglu.”
Turkey’s President Recep Tayyip Erdogan, who was sworn into his third presidential term on Saturday, changed almost all of his cabinet members except for the ministers for health and culture.
Fidan, Erdogan’s intelligence chief and a former soldier, was named as the new foreign minister replacing Cavusoglu, who has served in the role since 2014.
One of Erdogan’s closest aides, Fidan has headed the National Intelligence Organization (MIT) since 2010 and before that was an adviser to Erdogan in the prime minister’s office.
