US companies used to release lots of papers. You can go back to when they did, and see for yourself how many Chinese names there are on them. Or you can look at those which still publish a lot, like Nvidia.

Google is catching up, especially by the metric of "making money".

Meta from the start clearly had a strategy not of competing to dominate, but preventing their competitors from dominating by releasing open models and software. (You have them to thank you're not working in Tensorflow right now)
