I don't think of Taiwan or China as inherent hotbeds for fraud, no more than other Western countries (which isn't exactly saying anything).
If it's a significant order I would qualify this person very heavily. Technical questions related to the product I find do the trick quite well "Do you mind me asking what you're using the products for?". Scammers get scared off pretty easily.
Now with all of that being said, if you're sending something to China/Taiwan/Hong Kong there's a pretty good likelihood they may be ordering it to copy. If they say they want to be resellers of this product that perks my ears even more. They might do a couple of orders do gauge demand but eventually if it's easily copied they likely will.
