Why a Taiwan Strait invasion would be exceptionally difficult

Does China have a balanced fleet capable of a cross-strait invasion of Taiwan, and what would it still need?

Fleet balance alone cannot solve the defender's geography, decades of preparation, underwater threats, shipping congestion, and the uncontrollable economic and political escalation of war.

Chinese efforts to secure nearby waters follow a familiar pattern of state behaviour, but an invasion of Taiwan would confront a defender prepared for decades on mountainous island terrain. Massed ferries and landing ships would make the strait noisier, degrading anti-submarine awareness while giving Taiwanese submarines, drones, and mines more opportunities. Fighting in one of the world's busiest shipping corridors would also disrupt global trade and invite sanctions. Opening a war would sacrifice the political control authoritarian leaders often value because escalation develops its own momentum and its consequences cannot be contained reliably.
