The 66-year-old martial arts star - who rose to fame in the 1980's and 1990's for his roles in movies such as "Above the Law" and "Under Siege" - was granted Russian citizenship in 2016 and is a vocal supporter of President Vladimir Putin.
Steven Seagal is trading his martial arts training for diplomatic skills in his new role as the Russian Foreign Ministry's special representative to improve United States and Russian relations.
"I hope we can strive for peace, harmony and positive results in the world".
The Russian Foreign Ministry announced the actor's appointment on Facebook, saying his mission will include promoting relations between both the countries "in the humanitarian field, including cooperation in culture, arts, public and youth exchanges and more".
I take this honour very seriously indeed and I once again thank you for your friendship, strength and support.
"Everywhere you look in Russian Federation - the terms of Steven Seagal", wrote the editor of the Bureau of si-EN-EN in Moscow Nathan Hodge. President Vladimir Putin and Seagal are close friends, which is more than likely why this new position was given. "In global practice it is possible to draw Parallels with the functions of the goodwill ambassadors of the United Nations", - said the press service of the foreign Ministry in its statement.
Seagal, who occasionally appears on Russian state television, said he welcomed the appointment, Reuters reported.
In the interview, Seagal also praised Putin as "a great world leader" and a "brilliant tactician".
"I've always had a very strong desire to do all I can to help improve Russian-American relations", he told the Kremlin-backed television station RT.
It's not the first time Russian Federation has tried to give Seagal some sort of semi-official status.
