China considers Taiwan to be part of China. It just isn't considered an active rebellion at this time, although in the long term, China plans on returning it into their orbit.
To be fair, the Republic of China on Taiwan considers the Communists on the mainland to be in open rebellion against the lawful government in Taipei as well.
“China considers Taiwan to be part of China.”
That doesn’t mean it is.
” It just isn’t considered an active rebellion at this time, although in the long term, China plans on returning it into their orbit.”
That doesn’t mean Taiwan is in rebellion. Germany wanted to take over Europe. Were France and England in rebellion against Germany?
No.
