You'd be far better off with an accredited and ideally ranked MBA program, such as those offered by ESMT and Mannheim. An MBA like this will be better for you in virtually every way, from curriculum to post-program career support, something that you will most certainly need.
Also, read Duncan's post, "Do you need to speak the local language?"

Generally, students with beginners' or intermediate language skills cannot gain professional language fluency during their time studying without this sort of language learning being built into the programme. Working in English, generally living and socialising with other students who do not also have the native language, means that international students develop their language skills slowly.
I'd look at this as a reality check: In general, for most people, it's extremely hard to get business fluency by taking language classes, over only one year while also focusing on a full-time masters program. You'd have much better luck if you were able to do at least a year of full-time language learning prior to the program.
