It's a great question.
I will preface this by saying that I do not consider myself a China expert. I wrote a book on China-Russia relations and have done research over the past couple of years on that, but I do consider myself more of a Russia specialist.
The 2027 timeline we keep hearing about that Xi Jinping has given the People's Liberation Army is the date by which he wants the PLA to have the military capability to liberate Taiwan, “liberate” meaning to invade and occupy Taiwan by force. I don't necessarily think it means that the clock is ticking and that in 2027 it runs out.
Xi Jinping sees himself in the same way Putin does, as a historical figure, as an epochal figure. Therefore, by the end of Xi Jinping's tenure, I think his goal, which I think for him is non-negotiable, is to have Taiwan reintegrated. As to how that happens diplomatically, economically or militarily, I can't say.
