Asia is regarded as the rich East. Due to the rapid rise of the Arab Empire and the long-term wars against Byzantium, Persia, India and other countries, neither West Asia nor South Asia can be peaceful. Only China won unprecedented unification in the 7th century AD and made unprecedented achievements in politics, economy, culture and other aspects.
