Question

french colonies of vietnam was based on which two ideas?

Answer 1

French colonization was not based only on economic exploitation but was also driven by the idea of a 'civilizing mission'. Like the British in India, the French also claimed that they were bringing modern civilization to the Vietnamese. They took for granted that Europe had developed the most advanced civilization.
