Also, if they were so important to the Chinese people then they would still be talked about strongly in Taiwan which has a shared history going back to then and, as far as I know, they don't care nearly as much about it as the people living under the CCP.

Much to the dislike of the people actually living in Hong Kong. They would have preferred to never go back to being part of being China. This is another great example of CCP/Chinese aggression and colonialism against the world as opposed to their supposed persecution complex.
Of course the Mideast is largely unable to speak for itself because their culture, religion, and language leave them culturally isolated from the West. In many ways our treatment of the Mideast today, and their situation, is directly analogous to how we treated China in the past and the situation they were in. So I would argue what has changed has not been our behavior, but China's ability to defend itself.
Also, China will repeat the same missteps of the US in the middle east as soon as their first major interruption of fossil fuels happens. China is not immune.
It's long since time to move on.
China itself has committed many horrific crimes during that time.
Among these concessions was Britain claiming Hong Kong for themselves (which was only returned in 1997). Interestingly enough this happened twice! The legality of the opium was not completely clarified in the first war. After the second war the Brits forced China to legally accept their opium. And it just gets more sordid from there, with various "Unequal Treaties" continuing onward into the 20th century.
