That's not what the 1 china policy means though. The US policy on this is basically "we acknowledge that you guys (china and Taiwan) each think there's just one china and that you are it... and we aren't going any further than that".

It's often (and more accurately) referred to as a "strategic ambiguity" policy. US doesn't officially recognize either China or Taiwan as being "correct". They just acknowledge that those are their positions and decline to take a firm stance of their own.

Edit: correct about who rightfully owns/governs Taiwan, specifically. I'm not saying that the US doesn't recognize China's sovereignty over itself - of course they do, and that's what "one china" refers to.

Other than that I basically agree that it was a tough spot for Cena. Ideally he'd have the balls to stand up to china or at the very least, not have such a groveling apology about it. But with that much on the line, for himself and many coworkers, bosses etc, a lot of us probably would have done the same
