Tension along the Assam-Arunachal Pradesh border has once again raised questions over whether years of dialogue and agreements can prevent local disputes from turning violent.
On August 10, a dispute over alleged land encroachment at Mingmang Basti, also referred to as Bodoti or Mingmang Badati under the Gogamukh revenue circle in Assam’s Dhemaji district, turned volatile. According to multiple reports, firing left 11 to 12 people from Assam injured.
By August 12, the Takam Mising Porin Kebang (TMPK), the apex student body of the Mising community, along with the Mising Mimag Kebang and Takam Mising Mahila Kebang, imposed an indefinite economic blockade. Key routes, including the Silapathar-Likabali highway linking Dhemaji with Arunachal Pradesh’s Lower Siang, were choked. Vehicles bearing Arunachal registration plates were stopped, disrupting the movement of people and goods.
The situation worsened on August 13 when protesters from both sides allegedly resorted to stone-pelting. Police and CRPF personnel came under attack. Arunachal Pradesh Police fired rounds in the air near the Likabali entry point to disperse crowds. Tensions between the Mising community on the Assam side and the Galo community across the border also sharpened.
Amid the escalation, both state governments moved to contain the situation. Assam Chief Minister Himanta Biswa Sarma said, “Assam and Arunachal Pradesh share a bond that goes far beyond boundaries.” He said most differences had already been resolved through dialogue and friendship, with only 52 villages remaining under discussion. “Boundaries may define our States, but they can never divide our hearts,” he wrote on X tagging Arunachal Pradesh Chief Minister Pema Khandu and Union Home Minister Amit Shah.
Khandu welcomed Sarma’s statement and stressed the deep historical, cultural and fraternal ties between the two states. He urged people on both sides to maintain peace, harmony and mutual respect, saying differences must be addressed through dialogue.
The latest flare-up comes along an 804.1-kilometre inter-state boundary with roughly 1,200 disputed points. The dispute has roots in colonial-era demarcations, particularly an 1873 line that sought to separate Assam’s plains from the hills that later became Arunachal Pradesh.
After Independence, Arunachal evolved from a centrally administered region into a Union Territory and finally a full state in 1987. Claims of encroachment, competing land use and incomplete ground-level demarcation have repeatedly triggered local confrontations despite high-level agreements. Assam told its Assembly in late July that Arunachal had allegedly encroached on more than 16,000 hectares, while Arunachal has its own counter-claims.
There has also been significant progress towards a settlement. The Namsai Declaration of July 15, 2022, signed by Sarma and Khandu, reduced the list of contested villages from 123 and established regional committees for joint verification.
A formal Memorandum of Understanding followed in New Delhi on April 20, 2023, in the presence of the Union Home Minister. It declared a full and final settlement for the listed villages and committed both sides not to add new claims. Of the original 123 villages, differences over 71 have been resolved, while the remaining 52 continue to be discussed through reconstituted regional committees.
In February 2026, the first official border pillar was erected at Seijosa in Pakke Kessang district, marking a shift from agreements on paper towards physical demarcation.
The latest violence took place in an area where ground demarcation remains incomplete. Such areas remain vulnerable to disputes over farming, settlement and alleged encroachment. The TMPK and allied organisations have demanded the arrest and handover of those responsible for the August 10 firing, an early resolution of the remaining border issues and an end to alleged encroachment.
Sarma has described the incident as essentially a local land dispute rather than a state-to-state conflict. He has also pressed Khandu for a proper inquiry and punishment of those found guilty. Khandu has assured an impartial investigation.
Both governments have kept communication channels open through chief secretaries, directors general of police and ministers.
The political signals point towards de-escalation. Both chief ministers have publicly stressed brotherhood over confrontation and renewed their commitment to completing the remaining talks. The regional committees, the Namsai Declaration and the 2023 MoU provide an existing institutional framework for resolving the remaining disputes.
However, lasting peace will require more than political statements. Incomplete demarcation in sensitive areas continues to leave room for local disputes to escalate. Community organisations on both sides remain active. Trust will depend on visible action, including a transparent investigation into the firing, restraint by security forces and faster joint verification of the remaining 52 villages.
For now, the message from Guwahati and Itanagar is clear: dialogue must take precedence over confrontation. Whether that message holds on the ground in Silapathar, Likabali and Mingmang will determine whether the latest violence remains a temporary flare-up or becomes another reminder of the human cost of an unfinished border settlement.
The two states have already travelled a long distance towards a settlement. Completing that process remains the strongest path to lasting peace.
