As usual the title of this video is intentionally misleading.
Taiwan was not expelled from the UN. The representatives at the UN sitting in China's chair were expelled for not being considered the true representatives of the mainland Chinese government.
the order decree said
22 years after China's Civil War
Mao's representatives finally were allowed to take a seat at the UN to represent mainland China.
We can see the Chinese propaganda department very very very slyly and craftily at work here trying to portray Taiwan itself as an illegitimate renegade (see..see...looky here...
Taiwan even got expelled from the UN!!) ...even though this particular ruling had nothing to do with the Taiwan island itself.

The thing is this ruling sort of proves Taiwan's existence. It says the representatives of Taiwan lost their right to represent mainland China because they obviously have no control over it. But then you can claim mainland China lost the right to represent Taiwan because they obviously have no control over it either.
