Yes. Air superiority is important, however against the US, its gonna be challenging to contest for long term continuous air-superiority. The Batanes islands of the Philippines in the Bashi Channel is one area I suspect where USMC missile sites are gonna operate. It is some distance away from the Chinese coast. This is exactly what the US wants. To sit their Navy at the Western Pacific, some distance from the Chinese coast, back the Taiwanese separatists from behind and let them do most of the dying, while using Filipino islands as launch pads to launch missiles at Chinese ships and cities. They hope to be able the attrit the PLAN at the Bashi Channel before the Navy takes them on in the Western Pacific. That is the plan.
To counter this USMC "island launchpad" strategy, one thing I think China should do is to traditional area denial. Send barrages of ballistic and cruise missiles to pepper those islands with cluster munitions and small mines. First, that would catch some missile launchers out in the open. Second, those missile systems that were hidden would then have to contend with mines when coming out and moving around the islands to launch. Helicopters would also have a hard time landing on mine-infested islands.
If the PLAN can safely sneak submarines near the islands, they can also intercept US and Filipino Marine vessels moving between those islands too. But make sure to watch out for US subs and anti-submarine assets.
