well if he went through the trouble of such a long and expensive trip for her he must have had a great crush.
and if she truely feels he's THE ONE, then let it be, and just try knowing her boyfriend better and see for yourself if he really is truely in love with her, i know you must be concerned but try not to mendle with theire relationship too much and just be there for her when she needs you.
the cultural diference shouldn't be so much of a problem if they really love eachother ^^ everything depends on how opene minded they both are.
