@twsh Taiwan is a huge part of China's jingoism. They try to distract people from their own govts inadequacy - falling wages, poor social safety net, pollution - and channel that anger towards outside forces...namely Taiwan and (before they regained control) HK.
Good book about Taiwan
Forbidden Nation: A History of Taiwan by Jonathan Manthorpe
If you were keeping up with the umbrella movement in HK i found the book
Umbrella by Kong Tsung-Gan
to be an interesting read.
