That is only to be expected. China has the cash and the manufacturing capacity to do exactly that. The China of today is pretty much the same as the US of 1942: plenty of skilled workers, plenty of manufacturing resources, and plenty of cash for capacity to expand as required. The US of today is similar to the position that Germany or Japan were in back in 1942: not enough skilled workers or resources. And not enough factories even if the US did have those workers. And then you can also add in the crumbling transport and other infrastructure.
