The Chinese are very pragmatic, they cannot dump their dollars fast enough without incurring a major loss themselves, I doubt they will do anything drastic. As fas as Taiwan, I think they have a 25 years plan for it, slowly transit to a centralised capitalistic system (hybrid between normal capitalism and centralised economy) into which Taiwan will have less of an objection to rejoin. Thus, unless Taiwan insists on declaring independence, just smoke, but no real fire.
