True innovation means to develop or do something not done elsewhere before. The products you listed sound good, but they are certainly not innovative.
China, IMO has both innovative product and services as well as lazy copycats. Because the copycats are so many in number, we often don't regard the innovative stuff coming from there as well.
I bought a Huawei matebook laptop this past year. It was very cheap but looked cool - like a macbook. Funny thing though, the windows software was bootlegged and I had to use my institutional registration to get Windows software.
I used to use Amazon's market place and have now stopped after accidentally purchasing Chinese fraudulent goods (I still use for digital content).
My exposure to Chinese tech and goods, while limited, has now totally predisposed me negatively towards them. I haven't seen any innovative product personally. Just inconvenient knock off which have effectively stolen my money. If all Chinese tech goods were taken off the market, innovative or not, I would be happier knowing that I could start using a more trustworthy Amazon market place.
"If all Chinese tech goods were taken off the market" then which tech goods would be left? Are there any tech goods that include no Chinese components? What % of Chinese components is acceptable to you (assuming non-zero)?
What is different about China is an attitude. It was crystallised for me by a Australian Documentary titled "Two Men in China". One of those men was formerly Australia's chief scientist. They walked into a typical Chinese apartment. Very small, but it had all the latest gadgets. Then they showed the doors had fallen off some cupboards. In fact a whole pile of things had broken a few weeks after the couple had moved in. This was considered perfectly normal - they even had a word for it (which I forget).
In extreme cases it leads to things like baby formula suppliers adding melamine (a poison) to get the protein readings up to spec. (Australia's baby formula industry has done very well out of that little episode, so well there fights in the baby food isles appears on the nightly TV news as Chinese expats empty the shelves to make a quick buck. Turns out that _really_ pisses of local mothers with a hungry baby in their arms.) If you read stories on HN you come to the conclusion this attitude must pervade the entire business culture. Building falling down because of sub-par concrete, stories of "we sent them a spec, they built it well for a while, then someone notices part X had been replaced by a cheaper version" is a very common thread. Anybody who does business in China has to spend an inordinate any of money verifying all their suppliers are not cutting corners.
Americans are coming face to face with this now Amazon has allow the Chinese suppliers unrestricted access. Fake products, fake reviews, fake suppliers, fake purchases on other products leading to critical reviews, bribes for fake reviews - any scam that might work even only for a short term is being tried. Now imagine living in the country where that is how all business is done. Is it is at all surprising someone bought a system with face recognition, only to discover later it could be fooled by a photo?
If you are thinking China can't innovate you are just plain wrong. If you are pinning your hopes they will be perpetually held back by corruption you might be right (things look bleak under the current leadership) - but it's also possible they could turn into another Taiwan or South Korea, albeit with 1.3 billion people. If that happens we will see innovation on a scale we have never seen before.
