re lululemon, sure, has the Chinese innovate on what to produce and make such nice product as at now on their own? it's the input and design from the west plus the workmanship and experience that give them the current product quality.
can the Chinese work on it and make it even better in the future? hard to say yes or no.
usually, the west design or innovate, east copy and make it better via cheaper etc. this was the past, future, also unknown, that's why the war for innovation is really heating up for AI!
For EV, Chinese has won it so far with the decent quality and low price. They lost it a few years ago with BYD m6 or something, a junk.
