I can relate to your experience, prior to my mba I worked in manufacturing in China during 3 years therefore I do share part of your stories and I also had some interest in emerging markets. First you need to realize that you will certainly be considered as an applicant for the "diversity" bucket (other end up in "consultant", "bankers", "indian with IT background", ...) therefore you need to capitalize on your profile and on what you would bring to the class through your essays and interviews: explain how different is your job, how you had to adapt yourself to a new culture, how you took responsability and shape your business, how you learn ad lot of new business skills in china, etc... Overseas you have usually a lot more responsabilies and it's important to describe all this while stating that you also plan to leverage this into a more corporate type of work...Any experience is good, what's important is how you present it !
I think your profile will be fine, you need to work very well on how to explain step by step and in a rationale way the transition you plan to make to finance. You going into an MBA is not a problem however you moving into finance is the real question....this will certainly raise questions during interviews, you need to credible so work hard on that one. Good luck
