Not sure I believe that it can be done beyond a reasonable doubt. I still don't see what evidence there is that these things are Chinese. It's probably speculation and nothing more. It might still be true, but the attribution is likely highly speculative.

Balloons move with wind and can track the winds back to origin. I guess we can’t figure how far back the origin was but can make a guess.

Another thing is that other countries have radar. They likely tracked the balloon but ignored it. Russia probably won’t help but Japan might have seen it. Also, US is tracking balloons from before they enter Alaska.

We know the balloon is Chinese because they claimed. We don’t know what the other objects were.
