I agree with this, once the cold war died the need for US/China alliance died as well on top of this China was already on its own path to superpower-dom which meant it was always going to compete with the US.
I dont think that Tianamen square was a anything more than an excuse to part ways as other nations have done much worse and still remained allies (Chile, Iraq to name a few).
