The statement reads that Seagal's portfolio in the unpaid position would be to 'facilitate relations between Russian Federation and the United States in the humanitarian field, including cooperation in culture, arts, public and youth exchanges'.
Seagal won't be receiving any payment for doing the job, which the ministry described as "the case of people's diplomacy meeting with traditional diplomacy". He has also been accused of sexual misconduct by several women amid the viral #MeToo campaign, which he has denied.
"I've always tried to do everything possible to help Russian-American relations to improve", Seagal, who hold both Russian and U.S. passports, said to TASS news agency.
The star has also spoken out in defence of Putin amid claims that Russian Federation meddled in the 2016 USA presidential election, the BBC reports.
Long before Seagal and Putin became buds, the dual citizen tried in jest to influence the Russian president's reputation overseas.
A Kremlin spokesperson cited Seagal's "warm feelings toward Russia" and his celebrity status as reasons for the gesture, according to Reuters.
For more than a decade Seagal, who according to his own website is 66, has been a regular visitor to Russian Federation.
Steven Seagal, a martial artist, is popular in Europe and Russian circles for his action movies.
Seagal's grandmother was born in Vladivostok, and the actor and Putin share a passion for martial arts.
