It is difficult to trust many Chinese products because of their reputation for making cheap knock-offs rather than innovating products. Also, China is known for theft of intellectual property, unreliable quality control, and using cheap and possibly poorly skilled labor. The "Japanese" knives made in China remain suspect. It seems that quality and sophistication have generally suffered in China, where gross output is valued more than quality and innovation. I'm sure there are great products made in China, but it will take years before their reputation improves. I will not be the first to buy a Chinese car, or knife, except for perhaps a Chinese cleaver.
On the other hand, it is certainly possible to manufacture very high quality and consistent products in China, especially items designed outside China and made for export, but there must be significant investment in quality control systems and in-house full time QC personnel or corners will be cut and quality will deteriorate.
The plethora of Chinese made "Japanese" knives on Amazon is astounding. I wouldn't trust any of them.
