Changes take time, and there are massive opportunity costs to moving your supply chain base elsewhere. If other countries can do manufacturing equally well (same quality, cost, legal environment, etc), but you already have your base fully established in China serving your entire global operations, moving to the another country gives you no benefits, and you face the risk of severe disruptions to your operations if anything goes wrong.
So the world will only move out of China if other countries like India can offer significantly lower cost at same quality, which they haven't been able to do, or if there are significant geopolitical risks to staying, which seems likelier by the day.
