China's Navy (Peoples Liberation Army Navy (PLAN)) has one slight problem, its chain of command reports to the Army. That is different from our organization which the Navy has high ranking Admirals equal to the Army's generals. Our Navy will develop their own doctrines subordinate to joint services needs. Chinese admirals build their navy subordinate to their Army's needs. The way I see it, China's navy is built to support their Army's needs to invade Taiwan. Question is what happens to the fleet after they take back Taiwan. If China wants to build a true blue seas navy, they must make their navy independent from their Army, otherwise they lose in the defense budget fights with the Army projects. That will be the first sign that China will build a blue seas navy to challenge US power in the Pacific.
Yes, Western militaries generally don't have unified command structures. Which is better? We'll see when the balloon goes up.
