Chinese strategy in a war with the USA:
In my opinion, in the event of war with the US, the Chinese strategy would be similar to that of a bullfighter in a bullfight.
1-provocation: with the banderillas the bullfighter provokes the bull and makes it tire. It would be the most difficult phase but China could use its satellites to identify and target a task force sent to support some ally in difficulty. They would be attacks with hypersonic weapons beyond the second island chain that would be difficult to achieve due to the length of the kill chain, but the minimum achievable result would be to empty the US Navy's warehouses and wear down its operations from the start.
2-bleeding: when the bull is tired and the bullfighter has demonstrated his worth, knights arrive and sink their long spears into the animal's sides, bleeding and bringing him close to death. In this case, China would begin to heavily attack American assets on site, such as bases in Japan, etc., always with missiles and even air power, the attacks would be orders of magnitude more numerous than those of the initial provocation, the US Navy would be worn out in its logistics chain with little chance of response.
3-lunge, final victory: the bull is now exhausted and stunned, it has no chance and yet it is the most dangerous part, the bullfighter ideally with a powerful thrust of the sword reaches the heart of the animal, piercing it, the animal collapses dead. China in this part should welcome American ships and residual ground forces in full force by multiplying attacks by fully using aircraft carriers, submarine destroyers and advanced bases in the South China Sea. The American forces would already be feeling desperate and with little operations left, the Chinese forces would take care of cleaning up the remaining units once the aircraft carriers were destroyed. At that point the Americans could opt for a nuclear surrender or escalation, hopefully surrender.
Option at all phases for china is to initiate to target with conventional hypersonic weapons continental usa (san diego) and hawaii in case usa commencing targets mainland china.
