I would need to analyze the situation. The CPC has established it will not do this for any reason except to protect Chinese national security interests. If it turns out that the USA delivers advanced missile "defense" systems and other nuclear capabilities including submarines, air power, and other plaforms and assets, then it will be all but strategically certain that China will be forced to use military action to push the USA off the island and out of the surrounding waters.
Given the analysis of the Ukraine conflict, it's possible that China may need to include other considerations that I am not fully up to speed on about American capabilities and American proxy war strategies.
In short, yes, I trust the CPC to only use military force when all other options for defense against the USA have been exhausted. This has been their policy and doctrine for a while and there are no indications of it changing anytime soon.
