In a significant move underscoring the strategic weight of India’s eastern theatre, the Indian Army will host a two-day seminar titled ‘Arunachal Pradesh: India’s Dynamic Frontier’ on February 13-14, 2026 at Dinjan Military Station in Dibrugarh. The programme will focus on the geopolitical, security and developmental dimensions of Arunachal Pradesh.
Notably, the Northeastern state remains central to India’s border management and strategic posture along the Line of Actual Control (LAC), especially as the China question always comes attached to it. The upcoming seminar will be organised by the Dao Division under the aegis of Spear Corps.
Strategic importance of Arunachal Pradesh
Largest among the seven states located in the North East part of India, with an area of 83,743 square kilometers, Arunachal Pradesh shares its borders with the neighboring countries of Bhutan in the west, China (Tibet) in the north and northeast, Myanmar in the east and southeast, and the Indian states of Assam and Nagaland in the south.
Interestingly, it shares the longest international border with China (1126 km), followed by Myanmar (520 km), and Bhutan (217 km). Arunachal Pradesh forms a vital part of India’s eastern frontier, sharing a sensitive border with China. The region has witnessed heightened infrastructure activity, military modernisation and strategic recalibration in recent years amid evolving security dynamics.
Given its terrain, connectivity challenges and proximity to contested areas, the state plays a pivotal role in India’s deterrence posture and forward defence strategy.
Dinjan seminar on Arunchal Pradesh: What is the aim of the programme?
The Army said the seminar seeks to promote deeper understanding of Arunachal’s geopolitical complexities while charting a roadmap for integrated development and security.
By bringing together security experts, policymakers, civil administrators and academicians, the initiative reflects a broader push to align operational preparedness with socio-economic development in border regions.
“Our goal is to generate valuable perspectives that strengthen strategic awareness and reinforce civil-military cooperation in this vital frontier,” The Times of India quoted a Spear Corps spokesperson as saying.
What key themes will be discussed?
The seminar will be structured around three core thematic pillars – the unique socio-cultural fabric of Arunachal Pradesh; evolving border security dynamics and operational challenges; and critical infrastructure and development projects underway.
The Army has emphasised a people-centric approach, ensuring that development initiatives – roads, connectivity, logistics and civic infrastructure – move in tandem with national security priorities.
How does development strengthen national security?
The discussions are expected to highlight how inclusive growth, improved connectivity and local participation enhance stability along sensitive borders. Officials stressed that border infrastructure and community engagement are essential force multipliers, particularly in high-altitude and remote areas where civilian resilience directly supports military readiness.
The seminar aims to strengthen civil-military synergy and adopt a “whole-of-nation” approach to securing India’s eastern gates.
Beyond conventional defence preparedness, the Army’s initiative reflects a broader understanding that safeguarding the eastern frontier requires integrated planning like combining operational readiness, infrastructure expansion, and local empowerment.
