While China has a poor track record for quality in some instances I can say that quality is largely determined by how manufacturing is managed and how well specifications are written. I think that the China built stuff at AutoZone and Advanced Auto is decent stuff largely due to the fact that those companies would not risk a class action lawsuit for inferior manufacturing standards and have put adequate controls in place. As a part of my job I purchase injection mold tooling from China on a regular basis with better quality than what I get in Canada and the US. If my customer (GM, Ford, Toyota, Mercedes...etc.) allowed me to purchase all tooling in the US I would do it but the competitive market does not allow. Many high quality products come directly from China. Apple I phones and Bose products are a few that come to mind.....poor specifications and lack of up front engineering is what gives some Chinese products a bad name...(Children's toys made with hazardous materials, etc. etc.)
