Intel has fabs all over the world, including many in the US and some in China[1]. Whenever people talk about chip manufacturing they seem to only think about high-end cutting edge processes, when in fact the majority of quantity of chips produced are at non-cutting edge fabs that are spread all over the world and made by many companies that you haven't heard of, but also Intel.
However this was never about Intel manufacturing chips in Xianjing, it was about the long long tail of supply chain that goes into these ships from mines through to chemical supply companies up to industrial machinery supply and everything in between.
