Russia's Foreign Ministry said on Saturday it had made U.S. actor Steven Seagal its special representative for Russian-U.S. humanitarian ties, a role it said was meant to deepen cultural, art and youth ties between the two countries.

The Belgian spent half of last season on loan at Borussia Dortmund as he sealed a place in the Belgium World Cup squad . It has since been revealed that a passport issue has held him up in Brazil - but Sarri is not convinced.
Seagal is now officially going to develop relations between Russian Federation and the United States in the field of culture, art, public and youth exchanges, etc. "I take this honour very seriously", he wrote on Twitter.
Reacting to the appointment, Seagal said he was "deeply humbled and honoured".
Seagal's grandmother was born in Vladivostok, Russia, and the two men share a passion for martial arts.
After Russia's annexation of Crimea in 2014, Seagal called Putin "one of the great living world leaders" and even performed with his blues band in the annexed Black Sea peninsula.

Russian Federation isn't the only country offering overtures to Seagal. He's also visited with Chechen leader Ramzan Kadyrov and Belarusan President Alexander Lukashenko. Back in 2013, Seagal was Putin's choice to lead a special diplomatic envoy.
