Should the government restore public Khmer education in South Vietnam?

Should Vietnam help sponsor Khmer language education among the ethnic Khmer? In the past Khmer people have many pagoda schools in Vietnam and teachings are unrestricted because it was not monitor. But now time have change and subjects must be approved first. History about Khmer Krom people are omitted under pretext as anti-Vietnamese identity.

All imported text materials obtain from Cambodia by priest and monks must be screened and signed before it is allow entry into Vietnam to be used by it's Khmer Krom indigenous population.

Is this a fair and appropriate policy?
Should it be continue or should Vietnam embrace ethnic diversity by allowing for celebration minority cultural history and allow them to embrace and preserve their own unique identity.
