These are really interesting points. I'm not an expert but I'm not sure the last point is as simple. - The US does use subversion to ferment political instability, more or less using the same channels it did to overthrow nationalist governments around the world like Chile, Guatemala, Iran etc. The CIA trained the previous Tibetan regimes' aristocrats in Colorado and paradropped them back in China for a failed guerrilla rebellion Bay of Pigs style. - The CIA/NED actively throws millions at insurrections in China such as in Xinjiang, Hong Kong, Tibet etc. They're not hiding it in their website either. - The US may be less worried about China to start with since US military bases and its geopolitical allies surrounds China in every which possible (or relevant) way. China more or less does maritime trading at US's discretion. - Arguably, Nixon/US didn't exactly care about China more or less the same way the US didn't care about South Vietnamese market economy. Nixon personally just wanted to score a leverage on USSR.
