So just as a reminder about why China is saber rattling so hard at Taiwan,
the Republic of China's Navy is working on 8 SSKs with Japanese help. These are modern, if not quite top of the line, Diesel-Electric boats perfect for very quietly putting large chunks of the PLA(N) on the bottom. The CCP's subs are outdated Russian knock-offs. If Taiwan is ahead of Schedule, the Chinese don't have until 2025 to force Taiwan back in, they've got maybe two years. You can't conduct a massive naval invasion while subs are sinking your transports, or God help them, putting one of your carriers on the bottom. Xinnie the Pooh cannot afford a major loss of face and grumblings about maybe having lost the Mandate of Heaven.
The saber rattling is trying to convince Taiwan to give up without a fight, because a fight is uncertain and you just know the RoC would be posting videos of dead Chinese manlets on their beaches all over the Internet.
