Why did the french establish schools in southeast Asia?

To teach young generations of colonized land, that France is their ruler (Probably had propaganda education supporting the French presence in Southeast Asia.)

Explanation:

The French had colonized parts of Southeast Asia known as French Indochina or just Indochina. This consisted of countries; Vietnam, Cambodia, and Laos.  With them ruling over a territory far from its mainland, establishing schools allowed friendly relations with the locals in the colonies. This would allow to implement younger generations to look at France as a friend and true ruler of their land. Obviously this didnt work in the long run, but it was to establish a "Friendly" French presence in Indochina.  

to unite muslims and hindus in resistance against british colonialism.
