There's no way that without defeating them economically, or by forcing surrender from militarily inflicting massive causality, or by electing a Chinese government, Taiwan will ever surrender reunifying.

Militarily there's simply no way China could Beach troops on that Island without inflicting heavy bombing first of which they would sooner sustain heavy losses. Taiwan has ample anti aircraft, an airforce, missiles, artillery, army, navy, and submarines. By that point nukes would sooner make any attempts quite redundant. Because any allies would sooner be defending. They might swarm with drones and missiles, but any attempt would meet return fire causing greater civilian causalities on both sides before drawing a much greater global conflict.

Laughably China will have too wait much much longer for an economic or elected victory before attempting a fool's errand. Where it would be easier to obliterate rather than actually reunify and if by obliterating it would sooner be mutual.

An economic victory would largely be against Taiwan's allies, it might force their surrender. Although prior to that point conflict could have broken out anyway.
