Nah. just nationalized them. Problems solved. If Apple and their suppliers ever leave China, nationalize all of them.The local governments, and even the central government, have screwed themselves by allowing Foxconn to grow its Zhengzhou campus this big. It has become a "too big to fail" monster for the locals and the governments.
The governments should have limited the max size of industrial campuses early on and made Foxconn, and others, to spread investments over multiple cities in different provinces.
