The PRC seems content with the status quo because they're convinced that Taiwan will eventually come back into the fold of their own volition. What timeline that would happen on pretty much depends on the speed at which imperial decline makes the US incapable of meaningfully stepping in to prevent that and the Taiwanese either have mass uprisings demanding to rejoin the mainland or (far more likely) the Taiwanese bourgeoisie see the writing on the wall and start doing the math on how much money they get to enjoy before China clamps down on them at some point post-reunification, possibly being a nuisance to the larger state in the same way the Hong Kong ones are.
