Personally, as of this week I'm biased against ROC. The last taiwanese co I contracted with stole my IP by creating a new co in taiwan and selling my patents to them, then claiming that I had to sue in taiwan to get my royalties....obviously underhanded. This week, my current boss got fired b/c his taiwanese counterpart sent a fake letter in from the customer complaining about him. The taiwanese guy called and tried to explain that it was nothing personal, just business because he was having to share commissions with the US salesguy.
I've long been a supporter of Taiwan...but those SOBs would sell us out in a heartbeat if it came down to brass tacks, and I am losing any interest I have had to pay for their damn defense.
Doing business on the Chicom mainland, you usually have to sign something that says anything you bring (i.e. or concieve) inside their borders becomes property of the "people's republic." The Chinese will steal just as quickly, but at least they're upfront about it!!!
