Question

Why did they have this dilemma to teach French or Vietnamese?
Why did they even wanted to teach Vietnamese why not only French?

Answer 1

French was the official language of Vietnamfrom the beginning of French colonial rule in the mid-19th century until independence under the Geneva Accords of 1954, and maintained de facto official status in South Vietnam until its collapse in 1975. Vietnam contains the largest of the three Francophone communities in Southeast Asia, the others being found in Laos and Cambodia. French is spoken by over 5% of the population and is sometimes used in international relations and education.[1]
