>Taiwan was not under control or rule for the majority of the Qing dynasty.
Clearly you did not comprehend the linked article. Surely a regime that appointed bureaucrats to be stationed locally in their administrative areas for nearly 200 years means it was Terra Nullius all along!
By your logic British rule in India didn't begin until 1858 when the British has been colonizing India for 100 years prior. Good job being a disingenuous revisionist.
>People were not allowed to freely travel to the island until 1875. It was called a province for ~10 years.
The very fact that the Qing dynasty had effective immigration controls over a land they supposedly did not "control" or "rule" is a testament to them actually exercising control over a land they managed to govern. The Qing Dynasty did not exercise immigration controls over the Chinese diaspora in Southeast Asia, because they did control those lands. That is not the case with Taiwan. The existence of immigration control is proof of governance. The PRC had strict internal immigration controls for the first 30 years of its existence, modelled after the Soviet Union. Would you say either of these countries did not effectively "control" or "rule" the very territories that formed them?
>By saying that it belonged to the Qing dynasty, we are saying that Russias occupation of regions of Ukraine is legal and legit.
Your nonsensical comparison to Ukraine just further reaffirms that. Nobody said a word about Ukraine until you tried to shoehorn it with gross disregard of the history of Ukraine.
>They are there so therefore they must own it.
The Qing Dynasty ceased to exist 100+ years ago and they have very little to do with the ROC or the PRC of today despite the ROC technically having legally suceeded the Qing Dynasty. So whether the Qing Dynasty "owned" Taiwan has nothing to do with cross-strait politics of today. Would you deny Tsarist Russia "owned" what is modern day Ukraine? And are you aware whether Tsarist Russia "owned" what is modern day Ukraine has absolutely nothing to do with Vladimir Putin's personal claims? I'm talking about the rampant historical revisionism seen run amok in every English language discussion about Taiwan that is ultimately infantilizing the real issues faced by Taiwan, not whether the PRC "must own it" (hint: the PRC has never "owned it" and never deserves to "own it").
