Yes, this was my point about countries such as the Phillipines & Vietnam acquiring shore based anti-ship missiles. Sorting and targeting will require advanced military capabilities otherwise you may end up sinking a bunch of PLA "fishing boats". The PRsM will need quite advanced military capabilities such as F35's and space-based surveillance.
Area-denial across the Formosan Straits is a lot different to the South China Sea with Taiwan opting for shorter range shore based systems and mines.
