In case the wife does bring the suit, let's say she wants a divorce or what we call a "dissolution", obviously she will encounter jurisdication problem. Practically speaking, do you think she will be able to come to the states only for suing his huzband? Absolutely not. The only solution I can imagine for her is to sue this jerk in China. Well, even we assume she wins and gets a judgment againt him...
Where the hell can she enforce it? It's more likely than not that a US court will refuse to recognize a foreign judgment against property in the States, needless to mention that this decree is coming from a communist country.
So my conclusion is: law is powerless in protecting cross-border marriage.
