I'm not a strategist, and trying to stay as far as I can from politics, but unlike Russian invasion of Ukraine, where other countries utter strongly-worded sentences while buying as much Russian gas as they can get a hold of, Chinese invasion of Taiwan will not end well for China. Taiwan plays a vital role in semis, electronics, communication equipment. Nobody is particularly dependent on anything unique to China, on the contrary, China imports a lot of resources and food. Once this is cut off or made prohibitively expensive, China's economy will tank and the following social unrest will be unacceptable for the CCP.
