The air superiority requirement for China is actually very low. China doesn't even need air superiority over the beach, just the strait. The strategy to do so is simple: kick open the door with ballistic missiles and stealth strikers or point blank VLS launches from subs taking out SAMs, radar and any planes on the ground, then shoot anyone that takes off while they're still climbing in air to air.
But why not the beach? Because the PLA doesn't need to clear the beach to attack it. Once barges filled with FPVs can drop anchor within 5 km of the coast, its over. Everything down to individual infantry within 10 km of the coast gets cleared out by FPVs. Fiber optics or wired FPVs start off by kicking the door open against anti-drone soft kill, then RF controlled swarms go after the unprotected targets and calling rockets/missiles/airstrikes down on hard targets. Once the first 10 km is emptied of ATGMs and machine gun nests, a beachhead is secured and its done.
FPVs really are a game changer due to their massive volume and the PLAGF should be all in on FPVs of all variants: guided by RF, wired or AI, and with recon, HE and shaped charge payloads. They're the new artillery.
