Why Arunachal Pradesh Remains at the Centre of the India–China Border Dispute: Latest Border Claims Explained

Arunachal Pradesh has once again become the focus of India–China tensions after recent reports alleged increased Chinese activity near the Taksing sector in Upper Subansiri district. Some local groups claimed that the People's Liberation Army (PLA) had expanded its presence near disputed areas, sparking concerns about fresh border tensions. However, the Indian Army has officially denied these reports, stating that there has been no new Chinese incursion into Indian territory and that the situation along the Line of Actual Control (LAC) remains under constant surveillance. This has reignited public debate over one of Asia's longest-running territorial disputes.

The roots of the conflict date back to the 1914 Simla Convention, when British India and Tibet agreed on the McMahon Line as the boundary. India considers this the legal international border, while China rejects the agreement and claims nearly 90,000 square kilometres of Arunachal Pradesh, referring to it as "South Tibet." Beijing has repeatedly issued "standardised" Chinese names for places in Arunachal Pradesh, a move India has strongly rejected, asserting that renaming places cannot change the reality that Arunachal Pradesh is an integral part of India.

The region is strategically important because it shares a long border with Tibet and includes Tawang, home to one of the world's largest Buddhist monasteries. Tawang is not only militarily significant but also holds deep religious importance in Tibetan Buddhism. Since the 2020 Galwan Valley clash, both India and China have significantly increased troop deployments and invested heavily in roads, bridges, tunnels, airfields, and surveillance infrastructure along the LAC.

Although the Indian Army has dismissed the latest reports of fresh PLA encroachment, the controversy highlights how sensitive the border remains. Every report of unusual activity attracts national attention because of the unresolved territorial dispute between the two Asian powers. As diplomatic and military talks continue, Arunachal Pradesh will remain a crucial flashpoint in India–China relations and one of the most strategically important regions in the Indo-Pacific.
