Andy,
What David and JimB are telling you is correct but, don't think all the money spending is just in EMF's or the trip(s) to China this is just the begining, after the two of you decide to marry then there is of course all that expence but then there is more, much more, there are the fees for every thing you need to file for your lady right up to and including the airfare to your country, the visa process will drive you insane at times and try to break you savings account, after she is here then there are more things to file and they all have a fee, she will also need some things so there are the shopping trips.
Brother if you are not prepared to go all the way, then as these people are saying, don't bother to start, but if you do start and find the ONE then as JimB has said, you will be rewarded with a most wonderful woman that will encourage you to do better at all you do, will help you with everything, and will take better care of you then you Mom did and will show you her love for you every day for the rest of her life, of course that is unless you make her loss face then your a$$ isn't worth a single red cent.
Good luck and best wishes.
