Agree 100%China is perfectly capable of manufacturing quality products. They manufacture iPhones, after all. If a US or other company uses a Chinese contract manufacturer, it is up to them (the customer) to impose quality requirements on the manufacturer and to audit them regularly. But supply chain management is no easy task, nor is manufacturing a quality product in China. It is not something a small company could likely do easily. Which is why the Apples of the world can afford to do this, but the smaller, startup companies, not so much.
Anyone old enough to have lived through the 50's - 70's will recall that the 'Made in Japan' label was a mark of shame. That has not been the case since the late 70's. Which car is most likely to last a quarter million miles with minimal repairs - a Japanese or US made car. Yes, I know many Japanese branded cars are assembled in the US. But the Japanese company controls the supply chain and is ultimately responsible for the overall quality.
