I'm Chinese, but grew up in Germany and China (International school).
Have you considered the MSc Finance from LSE? That seems to fit your profile quite well. However, the admissions statistics are very competitive. 2000 applied, 92 places.
If you're serious about reputation, go for IC, LBS, Cass, and LSE. I also got a place at Cass, but had to turn that down, because I'm more interested in Science and Technology.
