The catch with any oversea manufacturing, not only China is that they have the technology and equipment to make top notch products, but are often not incentivized to do so because of the association and demand for low cost products. Like Japan in the '60’s, China could easily start making market leading products especially electronics, and are slowly making headway in certain categories.
Software - In the software realm, DVDFab, in it’s various editions, DVD, Blu-Ray, UHD, is the standard for optical disc ripping software.
LCD and OLED panels - Look at this Wikipedia article and most of the LCD and OLED panels (only) are made in China. Panels is the key word. The electronics in high end LCDs and OLEDs are proprietary to the manufacturer, but the panels in some high end, though usually not the state of the art HTDVs may come from China.
Solar Panels - A large solar company I worked for switched to Chinese solar panels, claiming that they were as good as or better than anything made in the U.S. How much of that is marketing hype and how much is true, I never knew. But after years of undercutting the market (in which it’s widely speculated China purposely price undercut), Chinese panels are rising in price, potentially leading to even better quality products.
Blank DVDs - CMC Manufacturing, based in Taiwan with factories in China makes the majority of blank DVDs on the market ranging from crappy, to marginal to top quality. Price and brand name (most of the brand name discs are second tier discs from CMC) have little to no bearing on the quality of the discs. The last two proven quality blank DVD manufacturers, Taiyo Yuden and Verbatim, bot based in Japan, have closed their Japan factories and sold their proprietary formulation data to CMC who now continues to produce these top quality discs in their factories.
Beware as other manufacturers, possibly CMC themselves are selling counterfeit Taiyo Yuden (which are very hard to find in the U.S.) discs. Even when Verbatim was still making their own discs (some by CMC under their strict direction), they sold CMC’s second tier discs under the Lifestyle label. Now, the situation has gotten far worse and it’s extremely difficult tell the the true top quality Verbatim AZO discs from the second tier generic ones. If you’re still buying blank DVDs, read this thread I started at videohelp.com on how to spot the true top quality Verbatim AZO discs. Currently the ONLY top tier blank DVDs readily available in the U.S. and most countries.
