Yes, strange bedfellows. The Taiwanese love Japan and hate mainland China. But even Japanese companies do strong business with mainland China, as do the Koreans. Look at the business done between the USA and commie China, IBM had strong ties there and even sold their PC business to Lenovo of China. It's all about the money.
OK, money, I get that. In my line of work, IP, I see that the PRC blocks - by being an obnoxious bully - the ROC from int'l treaties such as the PCT (Patent Cooperation Treaty) or the int'l trademark system (Madrid Agreement/Protocol). Costs my clients thousands more in each instance.
The U.N. pu$$ies?...crickets...
Well, given all that, I'd have hoped the ROC at least made the phones they sell themselves and gave the PRC the one finger salute. Guess I was wrong about that.
