Tai Nüa language, also Dehong Dai and Chinese Shan, a language of those Dai people living in the Dehong Dai and Jingpo Autonomous Prefecture, and the Shan in Myanmar.
Many citizens of Dehong Prefecture belong to the Jingpo-nation ethnic group, an official minority in the People's Republic of China.
Mong Mao or Mao kingdom (Mong is the etymological equivalent of Thai Mueang, meaning nation) was an ethnically Dai state that controlled several smaller Tai states or chieftainships along the frontier of what is now Myanmar and China in the Dehong region of Yunnan with a capital near the modern-day border town of Ruili.

For the "recruiter"/kidnappers the ethno-linguistic ties between the Jingpo citizens of Dehong and those of Kachin are an enabling factor, as is the ineffectiveness of Chinese-allied Myanmar police in this region of de facto independence (Cf. Nayoubeng Mountain militia); Interpol is of even less use, as Myanmar itself is a rogue state.
