In Kalimantan, since the 1990s, the Indonesian government has undertaken an intense transmigration program; to that end it has financed the relocation of poor, landless families from Java, Madura, and Bali. By 2001, transmigrants made up 21% of the population in Central Kalimantan. Since the 1990s, the indigenous Dayak and Malays have resisted encroachment by these migrants, and violent conflict has occurred between some transmigrant and indigenous populations. In the 1999 Sambas riots, Dayaks and Malays joined together to massacre thousands of the Madurese migrants. In Kalimantan, thousands were killed in 2001 fighting between Madurese transmigrants and the Dayak people in the Sampit conflict.
