Nan province is in the upper north of Thailand on the border with Laos and is home to large populations of tribal peoples.
On June 19th of this year, lowland ethnic Thai from Chiang Klang, together with Royal Forestry Department officers, local police, and Border Patrol Police, cut off access to a road leading into an orchard and farm area in Nan province. The blocked road is used by both lowland Thai and ethnic minorities (mostly Hmong) to access the orchards and forest; the roadblock prevented upland villagers from traveling into the lowlands (and vice versa).
