Senior officials of Tripura and Mizoram are set to meet in Agartala next week to discuss the long-pending inter-state border dispute along the 109-km boundary shared by the two Northeastern states, a senior Tripura government official confirmed on Monday, 27 July. The date for the meeting has not yet been finalised.

How the Dialogue Was Revived

Tripura Chief Minister Manik Saha took the initiative to restart dialogue with Mizoram, raising the border issue directly with Mizoram Chief Minister Lalduhoma during the 73rd plenary session of the North Eastern Council (NEC) held in Shillong on 4 June. Lalduhoma reportedly agreed readily when Saha proposed that the two Chief Ministers hold dedicated talks.

Saha also suggested a two-stage approach: senior officials from both states would first meet to discuss the dispute in detail, after which the Chief Ministers would convene to take the matter forward. According to the Chief Minister's Office (CMO), the Mizoram Chief Minister accepted this framework.

The 73rd NEC plenary was attended by Union Home Minister Amit Shah, Union Minister for Development of North Eastern Region (DoNER) Jyotiraditya Scindia, Minister of State for DoNER Sukanta Majumdar, and the Governors and Chief Ministers of all eight Northeastern states.

The Structure of Tripura's Borders

Bangladesh surrounds Tripura on its southern, western, and northern sides, accounting for an 856-km international boundary — nearly 84 per cent of the state's total border length. Tripura also shares a 53-km inter-state border with Assam and the disputed 109-km stretch with Mizoram.

A Dispute With a History of Flashpoints

The Tripura-Mizoram border dispute has remained unresolved for many years. Tensions typically flare whenever either state undertakes development or construction work in areas claimed by both sides. In one such incident, unidentified miscreants in May last year hurled moderate-intensity explosives at an under-construction tourism building at Phuldungsei village along the border in North Tripura district, causing substantial damage.

Police officials from both states visited the mountainous border village to assess the situation. Tripura Tourism and Transport Minister Sushanta Chowdhury subsequently held a meeting with senior district officials at Jampui in North Tripura district, where it was decided to reconstruct the damaged eco-tourism infrastructure. The buildings were being built on forest land at Phuldungsei at a cost of ₹3.12 crore under the Centre's Swadesh Darshan Scheme of the Union Tourism Ministry.

Residents on both sides of the border have long maintained that Phuldungsei village falls within the territorial claims of both states, making it one of the most contested stretches. Both states deployed additional security personnel in the area following the explosion, and the Tripura government took up the matter with Mizoram through official channels.

Ongoing Efforts at the District Level

Over the years, the district administrations of North Tripura district and Mizoram's Mamit district, along with officials of the Survey of India, have held several rounds of discussions to resolve the disputed patches. Mizoram-based civil society groups and student organisations have, on multiple occasions, opposed construction activities by the Tripura government in areas they describe as 'disputed inter-state border' stretches.

What Comes Next

The upcoming official-level meeting in Agartala is expected to lay the groundwork for a subsequent Chief Minister-level summit, which would be the first such high-level engagement specifically aimed at resolving the boundary dispute. Whether this round of dialogue produces a durable settlement will depend on both sides' willingness to move beyond the positions that have kept the dispute alive for decades.
