You could start by referring to how the 7th Fleet Commander said this months ago,
and I cited it then. It's certainly odd to me how often you "forget" such things:
Adm. Thomas said he sees China’s recent actions around Taiwan as an extension of the “might makes right” mentality he said the country has shown in the way it has militarized the South China Sea. China’s expansive claims in the South China Sea overlap with those of other countries in the region. It has during the past decade built artificial islands in those waters, equipping the outposts with military infrastructure and equipment.
“They’ve completely militarized those islands,” he said. “They already have all the bunkers they need, they already have all the fuel storage capacity they need, the ability to house troops, they have the missiles, the radars, the sensors.”
China has the world’s largest navy by size, though the U.S. has more-advanced warships, including a larger aircraft-carrier fleet, giving it a qualitative edge. Adm. Thomas said China is turning out navy ships at an impressive rate, while the U.S. doesn’t have as many shipyards producing navy ships as it needs. China, for instance, is producing its Type 055 destroyers—a large and heavily armed surface ship, also known as the Renhai-class cruiser, that has become a symbol of China’s naval modernization—at a much greater rate than the U.S. is producing guided-missile destroyers, he said.
“Capacity has a quality all of its own,” he said.
Difficulties China might have coordinating across different branches of its armed services, which is how modern militaries operate, has long been seen as a potential weakness for the country’s military. But China has made progress on that front, Adm. Thomas said. Aircraft from China’s air force are flying across water, whereas only its navy undertook such flights four years ago, he said.
“They are more joint than they were a year ago, three years ago, five years ago,” he said.
