Re: Evidence? Anywhere?
Chinese carriers are "encouraged" by their government to use Chinese-made equipment. But this is done "quietly".
The difference with the American policy is broadcasting this across the world and "encouraging" American allies to follow the edict "or else".
It does not help that the American-branded equipment are all made in China, where labor is very cheap, but cost double the price (or more), less feature and less "user friendly".
