Context

• Recent reports of Chinese People’s Liberation Army (PLA) transgressions in the Asaphila, Taksing and Longju areas of Arunachal Pradesh have raised serious concerns about India's territorial security.
• Although the precise nature of these developments remains unclear, official statements and local reports indicate growing tensions along the eastern sector of the India-China border.
• China's actions may reflect an attempt to expand its territorial influence through incremental intrusions, similar to its strategy in Eastern Ladakh in 2020.

Emerging Chinese Transgressions in Arunachal Pradesh

• On October 22, 2026, ITBP Director General confirmed that face-offs between Indian and Chinese forces had occurred at several locations in Arunachal Pradesh and were continuing.
• Reports indicate that a stand-off had persisted near Asaphila since late July.
• Following a confrontation near Maja, close to Longju, Chinese forces reportedly returned in greater numbers and established camps approximately six to seven kilometres inside the LAC, as perceived by India.
• The confrontation continued despite meetings of the Working Mechanism for Consultation and Coordination (WMCC), Special Representatives and Corps Commanders, as well as Chinese President Xi Jinping's visit to India for the BRICS summit in September 2026.

Official Responses and Growing Concerns

• India's Ministry of External Affairs stated that border disturbances occur when Chinese forces deviate from established patrolling patterns.
• China maintained that its activities were normal patrols intended to protect territorial sovereignty.
• Arunachal Pradesh Chief Minister Pema Khandu acknowledged on October 29 that Chinese transgressions had occurred repeatedly because Beijing does not recognise the McMahon Line.
• Local organisations have also reported Chinese construction of roads, bridges and camps on traditional grazing and hunting grounds.

Historical Context and China's Expansionist Strategy

• Earlier instances of adverse Chinese possession were largely concentrated in the Namkha Chu and Sumdorong Chu valleys and Longju.
• However, an expansion into new areas, increased military presence or obstruction of Indian patrols would represent a serious deterioration.
• China may be attempting to replicate its Eastern Ladakh strategy of 2020, involving gradual territorial advances, temporary military structures and the creation of new ground realities.
• This approach, known as salami-slicing, enables territorial expansion without triggering full-scale military confrontation.
• Chinese commentators have also suggested that Beijing intends to enforce its claimed 1959 Line in the eastern sector, indicating a broader territorial strategy.

China's Claims and India's Rejection

• China rejects the legitimacy of the McMahon Line, established during the 1914 Simla Convention, and claims Arunachal Pradesh as part of its territory, referring to it as Zangnan or South Tibet.
• China's interpretation relies on historical map coordinates while disregarding the highest watershed principle underlying the original boundary alignment.
• India has consistently rejected this interpretation and the unilateral 1959 Line.
• The 1993 Agreement on the Maintenance of Peace and Tranquillity formally introduced the concept of the LAC without prejudicing either country's position on the final boundary question.
• The April 2005 Agreement further requires both countries to consider the actual state of border areas while negotiating a settlement.

Violations of Border Agreements and India's Diplomatic Position

• Several bilateral agreements require both countries to respect the LAC, avoid crossing it and refrain from unilaterally altering the status quo.
• China's increasing emphasis on territorial sovereignty while justifying its border activities contradicts the original understanding of the LAC.
• India's repeated reference to different perceptions of the LAC also creates diplomatic complications.
• The 1996 Agreement required both sides to exchange maps and establish a common understanding of the entire alignment.
• India must avoid diluting this commitment through vague formulations about improving understanding.

Diplomatic and Political Response: Lessons from the Past

• India must address serious confrontations through military, diplomatic and political channels rather than relying exclusively on border-level negotiations.
• In September 2014, Prime Minister Modi directly raised the Chumar transgression with President Xi Jinping, contributing to China's agreement to restore the status quo ante.
• In contrast, the situation in Eastern Ladakh following April 2020 remains unresolved.
• This demonstrates the limitations of prolonged negotiations without restoring the previous ground situation.
• India should adopt a multi-level response, combining military preparedness, diplomatic pressure and political intervention whenever territorial interests are threatened.

Conclusion

• Chinese transgressions in Arunachal Pradesh highlight the continuing challenge of protecting India's territorial sovereignty against Beijing's expansionist strategy.
• India must strengthen border infrastructure, surveillance, intelligence and regular patrolling while insisting upon compliance with bilateral agreements.
• The government must distinguish routine confrontations from developments that fundamentally alter the status quo.
• Strategic firmness, diplomatic consistency and public accountability are essential to prevent temporary intrusions from becoming permanent territorial advantages.
• Ultimately, transparency and national resolve will strengthen India's position against China's incremental expansion.
