Tbh china did a pretty good job in incentivizing moving out the supply chain during covid, with a complete travel ban to everyone for so many years. Western companies were practically banned for almost 3 years to visit Chinese factories for production, and doing this remotely is expensive and leads to bad QC. Many set factories in neighboring countries. For example I was surprised to get an ASRock motherboard made in Vietnam in 2022. Some iPhones are also made in India (and to catch a bird with two stones, get tax breaks from the Indian government)

Once a factory and its supply chain has left the country is very difficult that it will come back
