My gut feeling is those ships parked near the reefs are a ruse, a trap laid out for someone.
This isn't something that just happened at a low level that central government isn't aware of, this is carefully planned for good reasons. Central government can easily get whoever those ship belongs to to move if they want to, but they are deliberately playing dumb for a reason.
It would be difficult to dislodge that fleet unless you want to sink them all. Given the numbers involved that's actually not so easy and if one really is inclined to use force are you sure you're not walking into a PLA trap?
