Officially the post of Seagal's called "the special envoy the Ministry of foreign Affairs of the Russian Federation on issues of Russian-American ties and common cultural-historical heritage".
The foreign ministry said the unpaid role will be similar to the United Nations' goodwill ambassador positions.
According to CNN, Seagal attended Putin's swearing-in ceremony (marking the start of another six year term as president) in May, and Putin presented Seagal with his Russian passport directly in 2016.
The actor has been a Russian citizen since November 2016.
Cultural ties between Russian Federation and the United States have been hampered by the current diplomatic impasse.
After being announced as Russia's special representative on humanitarian relations with the United States, the exact nature of Hollywood star and martial artist Steven Seagal's mission has been revealed.

The senator met with members of the Russian parliament's upper house who serve on the foreign affairs committee Monday. He also held talks in Moscow with parliamentarians and pledged to block new sanctions against Russian Federation .
"In his new capacity Seagal is expected to promote the development and implementation of various projects of bilateral cooperation in the fields of culture, art, science, education, sports, public and youth exchanges, participate in relevant events on Russian territory and overseas and maintain contacts with US partners", it said in a statement. "I take this honor very seriously", he wrote.
Speaking to press after the announcement, Seagal said he was "sincerely grateful" to the Russian ministry for the honour.
However, the Michigan-born actor also had to pay a price for his allegiances. "In addition to my black belt, I'm now on a black list", the actor said in reaction, according to his spokesperson.
Seagal has also befriended other Eastern European leaders not exactly in the West's good books. Further advancing his credentials in the Slavic world is his Serbian citizenship, which he received in early 2016, prior to the Russian one, after he offered to set up an Aikido dojo in Belgrade.
