As to them being "Junk" , I have traveled in China, visited foundries and machine shops there. Almost every US company is there with some level of manufacturing. I recently purchased a new QF fuel pump, it lasted one race. It was junk. I returned it. I told them to keep it.
Poor QC is a production problem not always a location problem.
