Have you seen Taiwan? It's the world's largest floating ship. Nevermind that Taiwan also claims and is enforcing their claims on islands in Southeast Asian waters... oh look, Taiwan and Mainland China claim the exact same islands! Odd.

A large-scale naval landing is an immensely complicated logistical exercise even on relatively flat land like in Normandy. Imagine what it would be like on Taiwan?

Plus, China has simply projected no hard power away from its immediate vicinity. How exactly do you propose China would become the center of the universe without an aircraft carrier that can actually operate outside of Chinese waters?
