What’s stopping china from trying to take taiwan

With the Russian invasion of Ukraine underway and the support shown by the Chinese media towards Russia, what's stopping china from pulling the same stunt with Taiwan a few months down the line.

Now I know Taiwan is a major importance in supply chain and china might not want to risk crippling themselves but what if they do. Or they no longer care about the risk

Now I'm not saying it will happen it's just a hypothetical question as many many stocks will be affected by this
