I have some experience with Asian Universities, particularly Japanese.
First, take into account that having a Masters might boost a bit your application to PhD a bit, as long as you publish something over there. Also, if the profesor you are going with is unknown, it might not help you at all.
Second, many people think that studying abroad and traveling are similar things, when they are really not. You'll have to deal with the hardships of asian Academic culture, which are very different from the American ones.
You'll also have to deal with the hardships of life, be sure to know the language at least to communicate basic thoughts and deal with the fact that you might not like food there (Protip: Chinese American Food is somewhat different of real Chinese Food)
I would put more, but I would be edging on ranting, which I'm probably already are.
