The issue was that Chinese EVs are ahead of Western EVs due to aggressive subsidy and investment by the Chinese government to get ahead. So the market has been distorted which is what was "scary" according to the quite in the article that spawned the headline.
Having said that, I'm not sure I believe that Chinese EVs will be better quality. They may be cheaper and they may even have technically advanced but from experience of other Chinese products, quality is not a word I'd associate with them.
