Just look at the first one: papyrus was in use for nearly 5000 (five thousand!) years in Ancient Egypt and all over the Mediterranean before paper was conveniently invented by Cai Lun.
The term paper itself is actually derives from "papyrus".
It's really not any different with the rest of those claims.
Is it that paper is not an improvement over papyrus? This clearly does not stand.
Or that paper was not invented in China but in the classical world? This is contradicted by archaeological evidence.
Or that somehow the fact that the word paper is derived from papyrus in English means that it was invented by the west?
It really amounts to claiming to have invented the entire field of metalworking, when all that's invented is the casting process, whereas everyone was using forging techniques before then.
Disingenuous.
It's very difficult to see what you're actually trying to argue here. Chinese civilization generated a large number of important inventions, including (but obviously not limited to) the stirrup, paper, gunpowder, silk, the compass and paper money. It's about as silly to try to deny this contribution as it would be to deny the contribution of the Greeks to civilization.
I always find it funny/sad that Easterners in addition to suriving the crimes, have the extra task of educating the Western populations of the crimes committed in their names.
I expect you've noticed that every single country that is a victim of modern Chinese espionage was directly involved in destroying the chinese economy during the 19th to early 20th century.
US, UK, Japan, France, Germany, Russia (a few of the top offenders).
These nations can't simply commit a bunch of crimes, get rich, change the rules, then expect to be protected from past actions.
They do it all the time. When will the Chinese Communist Party pay for the famine which killed 2-6% of the population (lower bound is based on official government figures)? Probably never is when.
