| > they do speak Taiwanese Do you mean Hakka and/or Hokkien? Hokkien which is primarily spoken across the strait in Fujian. Hakka is primarily spoken in Guangdong, Fujian, and Jiangxi. Xi himself was the Party head of Fujian for most of his career and Xi's father was the Party head of Guangdong when he was rehabilitated in the Deng Xiaoping era. This is why most manufacturing in China ended up coastal Southern China - most Chinese Taiwanese trace their heritage to there barely 2-5 generations ago at most. The younger generation (post-1989) in Taiwan speaks and understands Mandarin. |
The issue is why would Taiwanese businesses care about the China market? Aside from the fact that the China market is massive, there is a simple answer: Taiwan and China have the same business language, and that is Standard Chinese aka Mandarin.
Yes, lots of Taiwanese people also speak other Sinitic languages that are not Mandarin, and are not mutually intelligible with it. And lots of Chinese people also speak other Sinitic languages that are not Mandarin and are not mutually intelligible with it. And even some variants of Mandarin itself are not mutually intelligible. But - outside of Cantonese in HK and Macau - none of those languages are used as the primary business language anywhere in either China or Taiwan, so it's an interesting side note but doesn't change the point.
All that said, aside from the Chinese market being massive, and the common language being convenient, there is a much bigger elephant in the room that explains why Taiwanese companies might not have a fun time doing business in China: politics.
It doesn't matter how much money Taiwanese companies might want to make if the CCP can threaten to turn off the spigot any time they want to influence Taiwanese politics, which unfortunately nowadays appears to be all the time. Sure, it's leaving a lot of money on the table, but doing business with Japan or the US or other countries that aren't run as a single party dictatorship whose leadership has a stated platform of dismantling your own government might be a less risky option.
