can you not grow your own sprouts.there is a lot of western veg in asia now? see if you can get someone to send you seeds.
It did cross my mind whilst I was back home to bring some seeds out with me, not specifically Sprouts. I seem to remember my mother saying Sprouts need a frost to be at their best and have the right taste, not sure if this is a myth to true, but we certainly don't have a frost where I am.
