Between 1968 and 1972, the area was the scene of fighting between Thai communist insurgents and the Royal Thai Armed Forces. Due to the difficult terrain, it was initially impossible to achieve success against the communists and tactics had to be changed. The military were able to convince the Hmong community present around the area to cooperate with the Thai government. This worked out perfectly and the communist insurgents surrendered without further bloodshed.[1][2]
