Arguing for border changes based on history can justify any border change. It's not functionally any different from "might makes right" because the invaded is unlikely to agree with that historical interpretation, nor are outside observers. If you have a reason based system for determining what is right or wrong, then you would have to look at what the citizens in Taiwan want otherwise you are violating people who committed no crimes against China and are experiencing threats to their way of life. You are literally talking about killing people for their land. You're on a forum that's largely American. Read the declaration of independence and see if it's confusing to you why an American would want to help Taiwan. The french helped us with our own independence. By the same logic America still belongs to the British. Any papers involved may as well just be "historical documents that no longer have any practical significance."
