Manabendra Narayan Larma requested autonomy in 1970. India used NEFA as a resettlement area for Chakma refugees. The India Tripura state had to deal with the issue of Chakma families. Agriculture, employment and education are dominated by Chakmas compared to Arunachal natives because they are more skilled and have a higher literacy rate. The issue of returning Chakma refugees from India to Bangladesh was raised in 1995. The hill tribes conflict with Bangladesh caused the exodus of 50,000 Chakmas to India from the Chittagong Hill Tracts. A 1992 deal between India and Bangladesh arranged that Bangladesh would take them back. A March 1997 agreement between Chakma leaders and Bangladesh provided for the repatriation to Bangladesh of Chakma refugees in Tripura. Both East Pakistan's partition and Bangladesh's independence caused an influx into India of Chakma refugees.
