they are parasites. They setup Fabs there to get preferential break and avoid import tariff yet they ONLY use their engineers; Korean and Tawainese to setup any type of equipment. No Chinese allowed in any setup. They used Chinese only as dummy operators and other logistics. They make an unspoken rule not to use any Chinese engineers . They don't want to teach Chinese anything. Chinese government originally thought they can teach Chinese something and bringing up local industrial chain. That's total wrong. Those Fabs only bring their own or other foreign suppliers. No Chinese suppliers are used. So they are parasites,dominating Chinese market and Chinese don't learn anything except as dummy operators. Chinese government need to kick them out of China so Chinese Fabs can start up. With them in China and dominating very difficult for China fab to succeed. Samsung fab at Xi'an, hynix fab at Wuxi and TSMC fab at Nanjing are PARASITES. No good for China's future.
