The Wa people (Wa: Vāx; Burmese: ဝလူမျိုး, [wa̰ lùmjóʊ]; Chinese: 佤族; pinyin: Wǎzú; Thai: ว้า) are a Southeast Asian ethnic group that lives mainly in Northern Myanmar, in the northern part of Shan State and the eastern part of Kachin State, near and along Myanmar's border with China, as well as in China's Yunnan Province.
At the time of British rule in Burma the Shan were the majority in Kengtung state, with other groups such as Akha and Lahu forming sizable communities.
Villages had a spirit healer (Tax Cao Chai) and the traditional way of dealing with sickness or other problems was to sacrifice a chicken, a pig or a larger animal, depending from the magnitude of the affliction.
According to local legend, the practice of cutting a human head was intended as a ritual sacrifice in order to improve the fertility of the rice fields.
Traditional villages had also shrines (Nyiex Moeg) where a buffalo was sacrificed once every year at a special Y-shaped post named Khaox Si Gang with an offering of the blood, meat and skin performed at it.
Thus, excepting Mang Lon where the Saopha resided, the British left the Wa State without administration, its border with China undefined.
[25] The prejudice continues in modern times when the Wa, who are economically not that different from other ethnic hill tribes in the area such as the Lahu people, are largely known for their rebel army and as being involved in drug trafficking, overshadowing other aspects of their culture.
The Wa regions in Burma were largely left alone until the 1950s, when remnants of Chiang Kai-shek's National Revolutionary Army fled the 1949 Chinese Communist Revolution.
During that time opium cultivation and sales grew and the ancient traditional life became disrupted, but also an administrative system that collected revenue and maintained a significant armed force, as well as a rudimentary infrastructure, ushered the Wa region into the modern era.
In return for agreeing to the ban of poppy cultivation and opium production the region experienced a massive influx of international development aid.
During this conflict the Wa army occupied areas close to the Thai border, ending up with the control of two separate swathes of territory north and south of Kengtung.
[29][30] Records of official seizures compiled by the United Nations suggest that in 2006 Myanmar was the source of half of Asia's methamphetamine, known in Thailand as yaba, and some experts believe that most drug labs are in areas under Wa control.
[33] Although little is known about the ancient history of the Wa, they are acknowledged by other dominant ethnic groups in Shan State, such as the Tai Yai, to be the original inhabitants of the area.
[34] They have been accused by Western governments of involvement in drug trafficking but have banned opium production since 2005 and have received United Nations aid in improving legitimate agriculture.
[35][36] It is set to be administered by the Wa people and its territory is between the gorges of the Mekong and Salween, in the east part of the Shan State, near the border with the Chinese province of Yunnan.
In recent times some Wa communities from Burma have crossed the border and settled in Thailand, where they have no official status as a Hill Tribe.
