The Wa is an ethnicity in the borderlands of China and Myanmar (Burma). In the 1950s and 1960s, their ancient land was divided for the first time by these two modern states. Before this watershed moment in Wa history, the Wa were famous as independent, practically invincible warrior-farmers, much feared in their region despite having no kings and no regular army. These Wa farmer-warriors were deeply engaged in their regional economy through trade in mining products, as well as in opium, and, as a result, the British colonial officers who tried but failed to incorporate them into their empire could not but marvel at the wealth of the Wa. Since the division, the formerly independent Wa communities have been transformed on both sides of the border: on the Chinese side, into drastically impoverished regular peasants under Chinese rule; and, on Burmese territory, since 1989, into peasants under a new type of Wa elite in the Wa state—a semi-state governed by the United Wa State Army (UWSA). Both in China and in Myanmar, the Wa are officially listed as an indigenous ethnic minority. In China, there is local autonomy in name only. In Myanmar, the UWSA is an ethnonationalistic Wa elite with an army of considerable power and occupies a fraught position in the geopolitics of the fragmented state of Myanmar, which the UWSA recognizes even as it seeks even greater autonomy. Both contemporary Wa societies are dramatically different from the past, although many cultural traditions continue.
