Seijosa in Arunachal Pradesh’s Pakke Kessang district witnessed a landmark development on February 22 with the erection of the first official border pillar between Assam and Arunachal Pradesh, marking a major step in implementing the Namsai Declaration aimed at resolving the long-standing inter-state boundary dispute.
Officials said the installation was carried out under joint supervision, with senior administrators and security officials from both states present to oversee the process.
The event was attended by the Deputy Commissioners of Pakke Kessang (Arunachal Pradesh) and Biswanath district (Assam), along with senior police officers, community leaders, village heads and local representatives.
The move follows the signing of the Namsai Declaration in July 2022, which laid the institutional framework for settling the boundary issue.
Since then, regional committees comprising Ministers and officials from both states have conducted joint field inspections, studied historical documents, and held consultations with border communities to evolve mutually acceptable demarcation plans.
Arunachal Pradesh Chief Minister Pema Khandu described the Seijosa installation as a historic breakthrough in the boundary resolution process.

He also acknowledged the role of Mama Natung and Assam Minister Pijush Hazarika, who heads the Regional Committee for Biswanath district, for their contribution to the process.
As per the report, the installation of the first pillar marks the beginning of a phased demarcation process that is expected to gradually bring clarity, administrative certainty and long-term stability to the Assam–Arunachal border areas.
