Why in the News?

India’s Northeast is facing a complex mix of border tensions, political instability in neighbouring countries, cross-border insurgency, drug trafficking and strategic competition among major powers.

More About the News

Three developments have brought these concerns into focus:

• Allegations by local organisations in Upper Subansiri district of Arunachal Pradesh about Chinese military infrastructure and possible encroachment near the international boundary.
• The growing strategic importance of the Siliguri Corridor, which connects the Northeast with mainland India, amid regional geopolitical developments involving Bangladesh and China.
• The continuing conflict in Myanmar, which has affected border security, displaced communities, India’s connectivity projects and the internal security situation in Manipur and Mizoram.

These developments show that the security of the Northeast cannot be viewed in isolation. It is closely connected with India’s foreign policy, neighbourhood relations and internal security.

India–China Border Tensions: The Arunachal Pradesh Challenge

India and China share an approximately 3,488-kilometre-long border, passing through Arunachal Pradesh, Sikkim, Uttarakhand, Himachal Pradesh and Ladakh.

However, the boundary remains disputed in several sectors.

• China does not recognise the McMahon Line, which forms the basis of the eastern sector boundary between India and Tibet. It claims Arunachal Pradesh as part of its territory and refers to it as Zangnan or South Tibet.
• The Line of Actual Control is the effective military boundary separating Indian and Chinese-controlled territories, but it is not fully demarcated or mutually agreed upon.

What is happening in Upper Subansiri?

In June 2026, the Nah Welfare Society, a local organisation representing the Nah tribal community in Upper Subansiri, alleged that Chinese forces had constructed roads, bridges and military camps in areas traditionally used by local communities for grazing, hunting and collecting forest produce.

• The organisation raised concerns about locations around the Taksing sector, including areas associated with ancestral grazing grounds.
• The Arunachal Pradesh Government said that the allegations would be examined through an investigation.
• However, the Indian Army rejected reports of recent Chinese encroachment, describing them as incorrect and without basis.

Therefore, these allegations should be treated as claims requiring verification rather than established instances of territorial loss.

Why is this important?

• Border infrastructure: China’s construction of roads, bridges and settlements near disputed areas can improve its military mobility and logistical capacity.
• Local communities: Border residents are important stakeholders because they possess knowledge of local terrain and contribute to India’s presence in remote areas.
• Strategic stability: Unresolved boundary issues can create misunderstandings and increase the possibility of military confrontations.

The 2017 Doklam standoff, which lasted 73 days near the India–Bhutan–China trijunction, and the 2020 Galwan Valley clash demonstrate the consequences of unresolved border tensions.

Siliguri Corridor: The Strategic Lifeline of Northeast India

The Siliguri Corridor, popularly known as the Chicken’s Neck, is a narrow stretch of Indian territory in northern West Bengal connecting the Northeast with the rest of mainland India.

It is strategically important because:

• It provides the principal land connection between the Northeast and mainland India.
• It is surrounded by Nepal, Bhutan and Bangladesh, with China located close to the wider Himalayan region.
• Any major disruption to this corridor could affect the movement of essential supplies, military personnel, trade and civilian transport.

Why has it attracted attention?

Regional political developments and China’s growing infrastructure presence in South Asia have increased attention towards the security of the corridor.

• Bangladesh’s Lalmonirhat airbase, located in its northern Rangpur Division, has attracted strategic attention because of its geographical proximity to the Siliguri Corridor.
• However, in May 2025, the Bangladesh Army’s Director of Military Operations reportedly clarified that there were no plans to upgrade the airstrip for military use.
• India’s Ministry of External Affairs has stated that it monitors developments concerning Chinese infrastructure and its possible strategic implications in Bangladesh.

In August 2026, the Union Home Minister reviewed the security of the Siliguri Corridor with senior officials from the armed forces, border security agencies and central and state governments.

The review covered infrastructure projects, border management, intelligence coordination and other security concerns.

Key concern: India must protect the corridor while maintaining stable relations with neighbouring countries and strengthening regional connectivity.

Myanmar’s Political Crisis and Its Impact on Northeast India

• Myanmar is one of India’s most important eastern neighbours. It shares a 1,643-kilometre international border with Arunachal Pradesh, Nagaland, Manipur and Mizoram.
• The military takeover in Myanmar in February 2021 triggered widespread political instability and armed conflict.
• The conflict involves the military regime, known as the Tatmadaw, and several ethnic armed organisations and pro-democracy resistance groups.

Why does Myanmar’s instability matter to India?

The conflict has weakened government control over several border regions and increased security challenges for India.

• Insurgent movement: Armed groups and other illegal networks can exploit difficult terrain and porous border areas to move across the region.
• Refugee movement: Violence in Myanmar has pushed people towards India’s northeastern states, particularly Mizoram and Manipur, creating humanitarian and administrative challenges.
• Cross-border crime: Weak border control can facilitate drug trafficking, illegal arms movement and other organised criminal activities.
• Developmental disruption: Insecurity has affected India’s infrastructure and connectivity projects in Myanmar.

India therefore faces the challenge of protecting its borders while responding humanely to people fleeing violence.

Free Movement Regime and Border Management

The Free Movement Regime historically allowed eligible members of recognised border communities living within a specified distance of the India–Myanmar border to cross the international boundary under prescribed conditions.

It recognised the traditional social, cultural and family ties of communities living on both sides of the border.

However, concerns over insurgency, illegal migration, arms trafficking and drug smuggling led the Ministry of Home Affairs to announce its decision to scrap the regime in February 2024 and recommend its immediate suspension.

• The Government has also pursued border fencing and regulated crossing arrangements.
• In January 2025, movement across parts of the Mizoram–Myanmar border was reported to be regulated through border passes, with specified entry points and conditions.
• Border management must balance national security with the traditional rights and livelihoods of border communities.

A blanket security approach without consultation can affect communities whose families, markets and cultural ties extend across the international boundary.

Manipur Crisis: The Internal Security Dimension

The instability in Myanmar has added another layer to the existing security challenges in Manipur.

The ethnic violence that began in May 2023 between Meitei and Kuki-Zo communities resulted in extensive loss of life, displacement and disruption of normal life.

According to figures presented by the Manipur Government in September 2026:

• 306 people had been killed and 49 were reported missing since the violence began.
• Around 60,000 people had been displaced during the conflict.
• Approximately 24,000 internally displaced persons were still living in relief camps, while others had been resettled.

The porous India–Myanmar border, the movement of armed groups and the availability of illegal weapons have added to the security concerns.

Role of drug trafficking

The Golden Triangle, comprising Myanmar, Thailand and Laos, is a major region associated with the production and trafficking of illegal drugs.

Drug trafficking has serious implications for Manipur and other northeastern states.

• Illegal drug networks generate money that can support organised crime and armed groups.
• Drug trafficking can weaken local communities, increase addiction and create public health challenges.
• Illegal cultivation of opium poppy and cross-border supply networks require coordinated enforcement and alternative livelihood opportunities.

Effective action must therefore combine border surveillance, intelligence sharing, action against drug networks, rehabilitation and sustainable livelihood development.

India’s Connectivity Projects and the Act East Policy

The Northeast is not only a sensitive border region; it is also India’s gateway to Southeast Asia.

The Act East Policy, announced in 2014, seeks to strengthen India’s economic, cultural and strategic engagement with Southeast Asian countries.

Myanmar is central to this policy because it connects India’s Northeast with the wider Southeast Asian region.

Two important projects are:

A. Kaladan Multimodal Transit Transport Project

• The project connects Kolkata and India’s eastern coast with Sittwe Port in Myanmar, followed by an inland waterway route to Paletwa and a road link towards Mizoram.
• It aims to provide an alternative route for connecting the Northeast with the Bay of Bengal.
• The Sittwe Port and waterway component was inaugurated in May 2023.
• The remaining road component, covering approximately 109 kilometres between Paletwa and Zorinpui in Mizoram, continues to face implementation challenges due to insecurity in Myanmar.

B. India–Myanmar–Thailand Trilateral Highway

• The project aims to connect India with Myanmar and Thailand through an international road network.
• It is expected to improve trade, tourism, transport and people-to-people relations.
• The political and security situation in Myanmar has delayed the completion of important sections.

Significance: These projects can reduce the Northeast’s dependence on the narrow Siliguri Corridor and strengthen India’s economic integration with Southeast Asia.

Important Government Initiatives and Frameworks

• Act East Policy: Promotes India’s strategic, economic and cultural engagement with Southeast Asia, with the Northeast serving as a key gateway.
• Border Infrastructure and Management Scheme: Supports the construction of border roads, fencing, floodlights, border outposts, helipads and other security infrastructure.
• Vibrant Villages Programme: Focuses on improving infrastructure, livelihoods and essential services in strategically located border villages to strengthen local communities and border development.
• Comprehensive Integrated Border Management System: Integrates manpower, surveillance sensors, communication networks and intelligence systems to improve border monitoring and response.
• Narcotic Drugs and Psychotropic Substances Act, 1985: Provides the legal framework to control and punish offences involving illegal narcotic drugs and psychotropic substances.
• Neighbourhood First Policy: Emphasises cooperation and stable relations with India’s immediate neighbours, which are essential for regional peace and connectivity.

Way Forward

The Northeast requires a comprehensive approach that combines national security, diplomacy, economic development and community participation.

• Strengthen border infrastructure: Improve roads, surveillance systems, communication networks and border outposts in strategically important areas.
• Promote local participation: Involve village councils, traditional institutions and border communities in monitoring and reporting suspicious activities.
• Strengthen diplomatic engagement: Continue dialogue with China on boundary issues and maintain constructive relations with Bangladesh, Myanmar and other neighbouring countries.
• Address the Manipur crisis: Prioritise peace-building, rehabilitation of displaced people, dialogue between communities and restoration of public trust.
• Control drug trafficking: Strengthen intelligence sharing, border checks and action against financial networks supporting illegal trade.
• Protect connectivity projects: Ensure the timely completion of the Kaladan project and the India–Myanmar–Thailand Trilateral Highway through coordination with regional partners.
• Promote alternative livelihoods: Support farmers, young people and border communities through skill development, agriculture, tourism and local enterprise.

Exam Hook – Key Takeaway

The Northeast is at the intersection of India’s national security, neighbourhood diplomacy and Act East Policy. Its long-term stability depends on secure borders, peaceful relations with neighbouring countries, strong connectivity, control of illegal networks and inclusive development of local communities.

Mains Question: Examine the geopolitical and internal security challenges facing Northeast India. Suggest measures to strengthen regional stability and connectivity.

One-line wrap: Securing Northeast India requires more than guarding borders; it requires building peace, trust, connectivity and prosperity across the region.
