I suppose it could be possible that China would try such a thing but it would be extremely foolish if they tried to advance any further than the immediate west coast states. I'm fairly certain the US govt has already ceded the west coast to china. Not only do they control the major ports there but the west coast has spent the last few decades being groomed to accept controls such as used by the CCP- anyone who doesn't believe that just needs to take a few moments to educate themselves on the laws passed in west coast states over the past few years.
The problem with that plan starts as soon as they reach the eastern borders of the west coast states where even the old widowed grannies own an arsenal and would die defending their homes and take as many invaders down with them as they could right up until their magazines run out due to the grip on their triggers holding even after their last breaths are taken. Just imagine what would happen to them even if they made it as far as Utah and the Mormons go after them. It wouldn't end well for the CCP at all!

As an American it's your responsibility to have your own strategic duck stockpile. You can't expect the government to do it for you.
