True. Not for the reason of colonialism. In china majority(98% plus) believe they are descendants of the Han dynasty. This unified view of belonging is what allows the single party system.
Total opposite is with India. The Hinduism religious vedic books dictates to segregate the society in the name of varna system(its successor modern day caste system) and even goes as far to restrict the education to only the priestly caste. This is the reason India is far behind in terms of education before the british era. Only after the conquest of British slowly everyone had access to education. This is the reason almost 95 percent of people are first college goers in India.
