Many people argue that it is hard for Western countries to pose economic sanctions on China by banning all (or most) imports from China, due to China's huge role in the world supply chain. I wonder what makes it hard for Southeast Asian countries (including India) to replace China and become new "world factory".
In my opinion, Southeast Asian countries (including India) have a bigger total population than China and cheaper labor prices. What makes it difficult for Western countries to move all (or most of) their factories from China to Southeastern Asia (very few of them are doing so as far as I know).
Please note that I am asking about the manufacturing industries, not about Wallstreet's investments in China (I suppose it is not hard for Wallstreet to withdraw their money from China)
