Cross-Border M&A Boutiques?

Have been studying Mandarin for 9+ years, highly proficient and approaching fluency. My finance vocabulary in Mandarin is also strong. Am a Caucasian male going to a semi-target double majoring in Finance and Chinese. Looking to get in to cross-border M&A working on China/East-Asia deals for a firm in NYC, HK, or Singapore.

I have been networking aggressively with bulge bracket and middle market firms in NYC and HK with success.

What are the cross-border M&A boutiques located in NYC, HK, China or Singapore that specifically focus on Asia transactions? Have found Morgen Evan, Somerley and a few other small groups. This area of investment banking seems to be one of the least covered from the research I have done, perhaps some of you can shed light? Any suggestions for me considering my background would be much appreciated as well.

Thanks!
