With most of a decades-old boundary dispute now behind them, Assam Chief Minister Himanta Biswa Sarma on Wednesday, August 12, 2026, publicly called on Arunachal Pradesh Chief Minister Pema Khandu to order an enquiry into what he described as an 'unfortunate incident' along the shared border — a request that arrives even as both states point to significant diplomatic headway.

52 areas left — and a 2023 agreement holding

Sarma's post draws a clear line between progress and the present trouble. Of the long-contested stretches along the Assam-Arunachal Pradesh border, the two states have resolved the majority of disputes, leaving only 52 areas outstanding. To address these, Regional Committees have been reconstituted — a mechanism that flows directly from a 2023 bilateral agreement both states signed to settle boundary differences through structured dialogue rather than confrontation.

That agreement was itself a milestone. For years, the Assam-Arunachal border had been a source of friction, with villages and land parcels claimed by both sides. The decision to institutionalise resolution through regional committees signalled a shift: two BJP-governed states, both under the broader umbrella of Sarma's North-East Democratic Alliance (NEDA), choosing cooperation over contest.

An 'unfortunate incident' — and a public appeal

What exactly triggered Sarma's appeal remains unspecified in his post. He does not detail the nature of the incident, but the decision to raise it publicly — and to address Khandu directly by name on a public platform — signals that the matter carries weight beyond routine administrative friction. Border residents and local administrations on both sides are the most immediately affected stakeholders whenever tensions flare along these stretches.

By framing his request as one between partners — using the respectful 'Hon'ble' and 'ji' — Sarma is careful to keep the tone cooperative rather than adversarial. The ask is for an enquiry, not an accusation. That distinction matters in the politics of the Northeast, where inter-state goodwill is both a governance tool and a diplomatic asset.

What the regional committees must now deliver

The reconstitution of Regional Committees for the remaining 52 disputed areas is the mechanism both governments are betting on. Their findings will shape whether the 2023 agreement holds its momentum or stalls at the final stretch. The outcome of Khandu's response to the enquiry request — and the pace of committee work — will be the real test of how durable this border peace actually is.

In a region where boundary disputes have historically outlasted political goodwill, the fact that two neighbouring states have narrowed disagreement to a defined, numbered list is itself a signal worth watching.
