Same as with Taiwan. It's an island off China and rebels flew there at some point and started to govern Taiwan as if it was theirs. China always insisted that Taiwan is part of China but because they never used military force to put an end to the game which those rebels played on that island it became harder for China to maintain the premise that Taiwan is in fact still part of China. Obviously the West has HUGE incentives to keep Taiwan seperate from China so will only portray one side of the story and the longer China was doing the objectively speaking right thing (not using force to exercise their right) the easier it is for the West to peddle the idea that Taiwan is in fact not part of China. It's almost like the West has been intelligently exploiting the good will of the East and I do feel like there is a lot of that going on between Ukraine and Russia as well.
Unfortunately there are no objective sources of news anymore and it's hard to really get a well balanced overview of the crisis. When I read on Wikipedia that for instance more than half of the Ukraine was not in favour of the Euromaiden protests, or other minor facts which shine a slightly different light on everything I am curious how much did the West contribute in stirring the crisis like we know they did in other countries in the world (Cuba, Middle East, Arab Spring, etc.)
