I am not sure about SE Asia but for N Asia, it is booming. Esp if you don't mind going to China. Firms like BCG, PA and Proudfoot are recruting from time to time. But pay may not be as high as UK (when I compare the salaries people post on this forum with the offers I receive before). When I received my offers last year, the salary level was around GBP26000 p.a. (thanks to strong GBP). Am not sure how this is compared with market rate.One note, is that in Asia people may prefer someone speaking a local language. If you are at senior level, however, then it may not be the case.
