“Khun Wang Royal Project Development Center, Mae Wang District, Chiang Mai”
Khun Wang Royal Project was established after His Majesty the King had visited Baan Khun Wang in 1980, and had observed that the land had been growing opium extensively. Therefore, the King assigned the Garden Plant Division, Thailand Department of Agriculture to demonstrate and breed crops on the area for supporting and passing on the technology know-how to highland farmers. This is to encourage them to do the plantation instead of growing opium.
