First of all, we should realistically see the destructive and constructive dual mission of colonialism since19th century. Although the colonialists are subjectively full of unquestionable aggression and plunder purposes, they involuntarily invested in many modern industries such as mining and transportation in colonies and semi-colonies under the temptation of high profits. For example, during the British rule in India, they built more than 65,000 kilometers of railways. At the same time, in order to facilitate effective colonial exploitation in colonies and semi-colonies, they also need to promote reforms aimed at destroying the natural economy and developing the commodity currency economy. Therefore, the colonists carried out western-style education in colonies and semi-colonies, trained new intellectuals, established modern political institutions and publicized western ideology and culture. In this way, the dual mission of colonialism was realized in both economic base and superstructure, which objectively promoted the reform and progress of colonial and semi-colonial society.

The colonialists and the bourgeoisie jointly overthrew the feudal class and promoted the political development of the colonies. . . . . . . . . . . . . . .
