Strikeforce light-heavyweight champion Gegard Mousasi has severed ties with M-1 Global, the Russia and Holland based organization which has co-promoted events with Strikeforce since last August.

M-1 Global also represents MMA superstar Fedor Emelianenko, who is part owner of the company, and it's president Vadim Finkelstein was the focal point of fruitless negotiations with the UFC to sign the legendary Russian fighter last year.

The alliance between M-1 Global and Strikeforce has raised the profile of both companies in the global MMA community, and helped pave the way for Mousasi to win the Strikeforce light-heavyweight title at Strikeforce: Carano vs. Cyborg.

Speaking to Sherdog.com, Mousasi confirmed by e-mail that he would no longer be represented by M-1 Global.

"After careful consideration, I have decided that it is in my best interest to part ways with M-1 Global," Mousasi wrote. "During the time I spent under their wing, M-1 Global, as a promoter and management company, allowed me to achieve many great things. I appreciate all they have done for me."

Mousasi currently has a contract directly with Strikeforce, so the end of his association with M-1 Global will not affect his planned fights with the promotion. Mousasi is expected to defend his title for the first time in April, when he will likely face the undefeated Muhammed "King Mo" Lawal at an event to be broadcast live on CBS.

Mousasi will also keep competing for Japan's Dream promotion, and plans to participate in the upcoming Dream light-heavyweight grand prix tournament, which is rumored to begin in May.
