Some Hmong groups fought as CIA-backed units on the royalist side in the Laotian Civil War. After the Pathet Lao took over the country in 1975, the conflict continued in isolated pockets. In 1977, a communist newspaper promised the party would hunt down the "American collaborators" and their families "to the last root". As many as 200,000 Hmong went into exile in Thailand, with many ending up in the US. Other Hmong fighters hid out in mountains in Xiangkhouang Province for many years, with a remnant emerging from the jungle in 2003.
