>How do you know that? How do you know that the Chinese aren’t exactly as uneasy about rapidly advancing AI capability

You can ask them, they live in China, not Narnia. I spend about two months in the country per year mostly for tech/work related reasons and I've not encountered that sentiment. For one they don't have these borderline religious schizophrenic breakdowns thinking they're bringing about the end of the world, most people just see this tech for what it is, a tool for productivity and automation like any other piece of software and they don't actually think about the US. They're competing first and foremost for Chinese customers, with each other, maybe some old CCP guy cares about America, the 20/30 something's care about competing with other Chinese companies for users.
