The reason to invest in China is not just for manufacturing ... although that is one good reason.
If you look at mainstream peer-reviewed international scientific and engineering research journals, you will find that the majority of articles (i.e. >50%) are from China, with perhaps 10% from the US (next largest) and then the rest of the world. This is the new reality ... totally different from even just a decade ago. The Chinese are investing huge amounts of money in science and engineering, and some of this works its way through to innovation and new ideas in the marketplace. Meanwhile the present US administration appears to be waging a war against its own (and still world-leading) science and engineering research universities ... that does not bode well for the future.
