Is it possible to have a Chinese marriage annulled and made void in the United States?

My girlfriend is a Chinese university student who is studying in America and I've know her for 3 years. A couple years ago when she was visiting home, she was raped by a man who happens to be the son of a close friend of my girlfriend's mother. She was socially pressured into marrying her rapist by both families. She has been suicidal and recently worked up the courage to tell her husband she wants a divorce. Both her mother and her husband refuse to allow the divorce to happen and both have threatened to kill her. We would like to avoid needing to move to China to carry out the divorce because this would greatly set back our lives. Is it possible to get this marriage annulled in the United States where we reside? She and her husband share no children nor property.
