Similar five needle pines occur in northern Việt Nam in the karst areas of the north east and to the southwest of Hanoi. These are sometimes identified as Pinus kwangtungensis which itself is treated as a synonym of Pinus fenzeliana Hand.-Mazz. on the IUCN Redlist. Subpopulations in Son La and Hoa Binh have been described as a separate species, Pinus eremitana Businsky. In other taxonomic works Pinus kwangtungensis is treated as a variety of P. wangii so that at the species level, it has a wider distribution in Việt Nam, possibly Lao PDR and southeastern China.
