'We have learnt many things about the functioning of the TTAADC in Tripura and it would help us to constitute autonomous councils for the tribals in Assam,' Barman said.

Tribal Welfare Minister Pramila Rani Bramha said that Assam currently has three ADCs under the Sixth Schedule of the constitution, but recently six other tribal groups had demanded separate ADCs under the same status.

The team visited several parts of Tripura in the past two days and held a series of meetings with Chief Minister Manik Sarkar and functionaries of the tribal autonomous district councils.

The region is also affected by militancy. According to a central home ministry report, 22 militant outfits are operating in Assam, Manipur, Meghalaya, Tripura, Nagaland and Mizoram demanding secession or autonomy for the tribals and indigenous people of the region.
