While not official, the US has stake in the game. They have actively prevented ASML euv machines from being distributed into China. A move against Taiwan is a big move against US interests so China and the US are at a stalemate. Should China attack Taiwan it will be at a time when the semiconductor industry is the least of our concerns and the US is in a significantly lower position than China. Right now it's just cold war era threats with both sides being paranoid of the other and both sides also being too afraid to act.
