Perhaps you are thinking of Hong Kong, which was reunited with the rest of mainland China about 13 years ago now.
No I'm thinking of Taiwan, everybody in industry knows anything sent to Taiwan within 6 months its in China (ask someone in defence about the F16 upgrades), how many Taiwanese work in China, its huge (millions), around 50% like the idea of joining China officially again. The only people not willing to see Taiwan as part of China is Americans lead by the Clinton's. Possibly because you Americans have wasted billions of dollars in Taiwan, trying to keep them separated only to find they are drawing closer together, both in terms of economy and geology.
Maybe send an aircraft carrier over, like in 1996, we can see if theirs is operational yet.
