People's Republic of China (Communist China) is technically a Marxist-inspired revolutionary state that imposed their single party dictatorship in China. The old government is in exile in Taiwan, and became democratic in the meanwhile, so the country is divided similarly to how Germany was divided, with the major difference that it is divided much more unevenly: The democratic Taiwaneese government controls only ~0.37% of the land and 1.68% of the population of whole China, as opposed to the FRG controlling ~69% of land ~79% of population of Germany reunification time.
Today, in addition to not caring about environment, being the most polluted country in the world and one of the firsts emitter of CO2, the communist Chinese government encourage child labour, they are violating human rights daily, and are also persecuting ethnic minorities, mainly in Tibet and Xinjang. It is not impossible to imagine some people will revolt against the Chinese dictatorship someday.
Has the old, government of China, which is in exile in Taiwan, any reasonable chance to get in control of China ever again?
