Fresh clashes erupted along the Assam-Arunachal Pradesh border in Dhemaji district, prompting police intervention and economic blockades, underscoring persistent inter-state boundary disputes despite the 2022 Namsai Declaration.

Key points

Dhemaji district witnessed violent clashes between Assam and Arunachal Pradesh protestors, leading to police firing to control mobs and imposition of an economic blockade against Arunachal Pradesh.

Takam Mising Porin Kebang (TMPK), Assam's Mising community student organization, initiated the blockade protesting alleged firing on 12 indigenous people from Assam over land encroachment issues.

Assam CM Himanta Biswa Sarma appealed for peace, emphasizing state boundaries should not divide people, while referencing ongoing efforts to resolve disputes through the Namsai Declaration framework.

Namsai Declaration (2022) between Assam and Arunachal Pradesh had reduced disputed villages from 123 to 52, establishing regional committees for resolution, but implementation challenges persist.

[GS2-Governance] The conflict reflects systemic failures in inter-state dispute resolution mechanisms under Article 263 of the Constitution, which empowers the President to establish Inter-State Councils.

[GS3-Security] The escalation to police firing indicates deteriorating law and order in border areas, requiring coordinated security protocols between state police forces under central oversight.

The dispute originates from 1987 statehood when Arunachal Pradesh was carved out of Assam, with unresolved territorial claims persisting despite a tripartite committee's recommendations.

Economic blockades as protest tools disrupt supply chains and violate Supreme Court rulings against such coercive methods, yet remain prevalent in Northeast conflicts.

Way Forward: Establish a time-bound arbitration mechanism under the Inter-State Council, deploy neutral central forces in disputed zones, and create joint land records with GIS mapping to prevent encroachments.
