Dude, you like have never heard of the Chinese civil war? And on which side the US was? The US supported the Guomindang of ROC because they should have been according to them the successor of mainland China. And long after they escaped to Taiwan, the US was putting sactions, economic blockades and manipulations on the PRC because according to the US they were just terrorists residing on the mainland, and in the beginning they wanted to re-establish the ROCs rule on the mainland.

You now demand from me to post some specific stuff that is never explicitly stated. You also won't find any document from Western countries in Europe recognizing that the Donbass is a region of Ukraine, what matters is when they recognize it's constution and accept that state on international levels.

Its time for you to put up some of that bold claims. I actually am interested, if you have any constitution or proposal of that Taiwan nation you keep talking, you can send it to me, I would really like to know what they have in mind if there is something like this.
