Where is french still widely spoken in mainland southeast asia?

The French colonized Laos, Cambodia and Vietnam in Southeast Asia. The countries had spoken French during and after the colonization period, however they stopped speaking it for a while until recently, since there has been a revival. This is to a larger extent in Cambodia and Laos and a little less in Vietnam. Vietnam during the colonization period experienced a sort of different relationship with the French language, as only the elites spoke French and people who occupied jobs which were seen as less professional, did not speak French.
