I don't think they really need to invade for this. It is almost in artillery range (there are rounds that can go 150km). They also could just send a big rocket barrage onto the factories. I assume it would be very hard to defend from such a short distance. Then most ports and cities in taiwan are towards east (with big mountains on the western side). Would be very bad if China decides to blockade it by shooting ships from their main land... Also very little the west could do imo. A land invasion in china or a nuclear war don't seem very reasonable.
