Dulong/Rawang is a Tibeto-Burman language cluster spoken on both sides of the China/Myanmar border just south and east of Tibet. Within Myanmar, the people who speak the Dulong language live in northern Kachin State, particularly along the Mae Hka and Mali Hka River valleys. In the past, they had been called 'Hkanung' or 'Nung', and have often been considered to be a subgroup of the Kachin. Around 1950, speakers of this language in Myanmar began a movement to use the name /rəwɑŋ/ to represent all of its speakers. The speakers in China, though, continue to use the name 'Dulong'.
