The species is under second-class national protection in China. Within Nonggang Natural Reserve in southern Guangxi, D. tonkinensis is the dominant tree species; however, its young leaves contributed only a minor proportion to the diet of the herbivorous monkey François' langur. In Vietnam, D. tonkinensis can be found in many national reserves. Its light wood was used to make furniture, chests, stationery products, match sticks, and clogs. References
