Unfortunately much of China’s perverse tactics (they’ve done this in a wide array of industries) is to steal patented tech and trade secrets from companies outside China, subsidize the manufacturing and development etc, then sell their product at an artificially low price which kills the original company and good faith competitors as they cannot compete with the artificially lower prices.

Then once the dust settles they’re the only company which can handle large order sizes required for supply chains to build downstream products, and the world becomes further reliant on them.

Security concerns and national defense aside, a prime example pre-ban was Huawei layer 1 infrastructure products which far exceeded feature density, and cost effectiveness than competitors due to the subsidies. They’ve done similar tactics with solar panels.

This doesn’t imply China or their state sponsored companies never create novel tech, but there’s a hugely perverse system whose purpose is to illegally undercut competition overseas with no real recourse from the victim countries outside of total company bans. And even then, people find a way around the bans and the damage is already done to the original companies.
