India Bhutan Relations

India–Bhutan Relations

  • India and Bhutan share one of the closest and most stable bilateral relationships in South Asia, based on geography, strategic trust, cultural ties, development cooperation and deep people-to-people contacts.
  • India and Bhutan share a 699-km-long border and strong historical Buddhist connections associated with Guru Padmasambhava, who travelled from India to Bhutan in the 8th century.
  • Formal diplomatic relations were established in 1968, while the resident missions were upgraded to full embassies in 1978.
  • The basic framework of bilateral relations is provided by the:
    • India-Bhutan Treaty of Friendship, 1949
    • Revised India-Bhutan Friendship Treaty, 2007.
  • The relationship today extends beyond traditional hydropower and development cooperation into:
    • Rail connectivity
    • Digital payments
    • Space technology
    • Renewable energy

Historical Background of India–Bhutan Relations

Ancient Cultural Relations

  • Civilisational relations between India and Bhutan date back several centuries.
  • Guru Padmasambhava, also known as Guru Rinpoche, travelled to Bhutan in the 8th century and played a major role in the spread of Vajrayana Buddhism.
  • India continues to occupy an important place in Bhutanese religious imagination as the land associated with:
    • Buddhism
    • Buddhist pilgrimage
    • Monastic learning.

British Period

  • The Treaty of Punakha, 1910 strengthened relations between British India and Bhutan.
  • Under the treaty, Bhutan agreed to be guided by British advice in its external relations, while Britain pledged not to interfere in Bhutan’s internal administration.
  • It is therefore more accurate to describe Bhutan as maintaining considerable internal autonomy rather than simply calling it a British protectorate.

Post-Independence Relations

  • India and Bhutan signed the Treaty of Friendship on 8 August 1949.
  • It became the foundation of modern bilateral relations.
  • Formal diplomatic relations were established in 1968.
  • India and Bhutan celebrated 50 years of formal diplomatic relations in 2018.

India–Bhutan Friendship Treaty

Treaty of 1949

  • The 1949 treaty institutionalised close political and strategic relations.
  • One of its provisions stated that Bhutan would be guided by India regarding its external relations.
  • With Bhutan’s political and diplomatic evolution, this arrangement increasingly appeared inconsistent with the principle of sovereign equality.

Revised Treaty of 2007

  • The treaty was comprehensively revised in February 2007.
  • The revised treaty removed the provision requiring Bhutan to be guided by India in foreign affairs.
  • Instead, it provides that both countries shall:
    • Cooperate closely on matters affecting their national interests
    • Not allow their territory to be used for activities harmful to the national security and interests of the other.
  • The revised treaty represents a transition from a historically asymmetrical framework towards a relationship based more explicitly on:
    • Sovereign equality
    • Mutual respect
    • Strategic cooperation.

Political Relations

  • India-Bhutan relations are characterised by high political trust and frequent high-level exchanges.
  • Bhutan’s transition to parliamentary democracy in 2008 did not disrupt the close relationship.
  • India maintains strong relations with:
    • The Bhutanese monarchy
    • Elected government
    • Parliament
    • Civil administration.
  • Prime Minister Narendra Modi chose Bhutan as his first foreign destination after assuming office in 2014, reflecting Bhutan’s importance under India’s Neighbourhood First Policy.
  • High-level engagement has continued through visits by:
    • King Jigme Khesar Namgyel Wangchuck
    • Bhutanese Prime Ministers
    • Indian Prime Ministers
    • Foreign Ministers and senior officials.

Recent High-Level Engagement

  • Bilateral relations intensified further in 2024–25.
  • Prime Minister Modi visited Bhutan in March 2024.
  • India committed substantial assistance for Bhutan’s 13th Five-Year Plan.
  • Prime Minister Modi again visited Bhutan in November 2025, reflecting sustained political engagement.

Economic Relations

  • India is Bhutan’s largest trading partner, both as an import source and export destination.
  • In 2024, India accounted for nearly 80% of Bhutan’s total trade.
  • Bilateral trade in 2024 was approximately ₹12,669 crore:
    • India’s exports to Bhutan: about ₹9,538 crore

  • These focus on:
    • Rural water supply
    • Health facilities
    • Schools
    • Roads
    • Local infrastructure
    • Agriculture.
  • HICDPs strengthen India’s development partnership at the grassroots level.

Hydropower Cooperation

  • Hydropower has historically been the cornerstone of India-Bhutan economic relations.
  • Bhutan possesses substantial hydropower potential because of:
    • Himalayan rivers
    • High gradients
    • Abundant water resources.
  • The arrangement is mutually beneficial:
    • Bhutan receives revenue from electricity exports.
    • India receives clean and reliable electricity.
  • Bilateral hydropower cooperation is governed largely by the 2006 Agreement on Cooperation in Hydropower, supplemented by a 2009 protocol.
Major Operational India-Assisted Hydropower Projects
    • Chukha – 336 MW
    • Kurichhu – 60 MW
    • Tala – 1,020 MW
    • Mangdechhu – 720 MW
    • Punatsangchhu-II – 1,020 MW
    • With Punatsangchhu-II commissioned in 2025, the combined capacity of major India-assisted operational projects increased substantially.
Mangdechhu Hydroelectric Project
    • Mangdechhu – 720 MW was commissioned in 2019.
    • The project was formally handed over to Bhutan in 2022.
    • It is an example of successful India-Bhutan hydropower cooperation.
Punatsangchhu-II
    • Punatsangchhu-II Hydroelectric Project – 1,020 MW was fully commissioned in 2025.
    • It significantly increased Bhutan’s power-generation capacity and electricity-export potential.
Punatsangchhu-I
    • Punatsangchhu-I – 1,200 MW has faced substantial construction and geological challenges.
    • Therefore, older notes treating all originally planned hydropower capacity targets as completed should be avoided.

  • India-Bhutan energy cooperation is gradually broadening from traditional hydropower towards:
    • Solar energy
    • Green hydrogen
    • E-mobility
    • Energy storage
    • Renewable-energy integration.
  • This diversification is important because Bhutan’s economic dependence on hydropower can create vulnerability to:
    • Seasonal river flows
    • Climate change
    • Project delays.

Renewable Energy Cooperation

  • Bhutan seeks to expand its renewable-energy capacity beyond hydropower.
  • Areas with potential include:
    • Solar power
    • Wind power
    • Green hydrogen
    • Pumped-storage projects.
  • India provides:
    • Large energy market
    • Grid connectivity
    • Investment

  • India-Bhutan cooperation can therefore evolve into a broader green-energy partnership.

Connectivity Cooperation

  • Physical connectivity is emerging as a new major pillar of India-Bhutan relations.
First India–Bhutan Railway Links
  • In September 2025, India and Bhutan signed an intergovernmental MoU for construction of the first railway links between the two countries.
  • Two projects are planned:
    • Kokrajhar–Gelephu – about 69 km
    • Banarhat–Samtse – about 20 km.
  • Their combined estimated cost is around ₹4,033 crore.
  • These railway links can:
    • Facilitate trade
    • Promote tourism
    • Improve passenger movement
    • Connect Bhutan more closely with Assam and West Bengal.

Gelephu and Regional Connectivity

  • Gelephu in southern Bhutan is becoming increasingly important in Bhutan’s economic-development strategy.
  • Improved rail and road connectivity through Assam could transform the region into an important gateway linking Bhutan with:
    • Northeast India
    • Indian markets
    • Ports
    • Wider South Asia.
  • The proposed connectivity is also relevant to Bhutan’s ambitious Gelephu Mindfulness City initiative.

Integrated Check Posts

  • The Darranga Immigration Check Post in Assam was inaugurated in November 2024.
  • It facilitates movement between:
    • Assam
    • Bhutan’s Samdrup Jongkhar region
    • Third-country travellers.
  • Improved border infrastructure can expand:
    • Trade
    • Tourism
    • Logistics

    • Environmental protection
    • Traffic
    • Impact on local transport operators.
  • Therefore, Bhutan is not currently participating fully in implementation of the BBIN MVA.
  • India, Bangladesh and Nepal have continued exploring implementation among themselves.

Significance of Bhutan for India

Strategic Location

  • Bhutan occupies an extremely important location between:
    • India
    • Tibet Autonomous Region of China.
  • Its western border lies near:
    • Sikkim
    • Chumbi Valley
    • Doklam Plateau.
  • Bhutan’s strategic stability directly affects India’s security in the eastern Himalayas.

Doklam and Siliguri Corridor

  • Doklam Plateau is disputed between Bhutan and China.
  • It lies close to the India-Bhutan-China tri-junction.
  • In 2017, attempted Chinese road construction triggered a 73-day India-China military standoff.
  • India opposed changes to the status quo because of the region’s proximity to the Siliguri Corridor, which connects mainland India with the Northeast.
  • Doklam therefore has significance for: Bhutanese Sovereignty + India-China Security + Siliguri Corridor

Siliguri Corridor

  • The Siliguri Corridor or “Chicken’s Neck” is a narrow land corridor connecting India’s Northeast with the rest of the country.
  • Any major alteration of the strategic balance around the Chumbi Valley-Doklam region could increase India’s vulnerability.
  • This makes Bhutan’s western boundary negotiations with China strategically important for India.

Bhutan–China Boundary Dispute

  • Bhutan and China do not yet have formal diplomatic relations and their boundary remains unsettled.
  • Boundary negotiations began in 1984.

Three-Step Roadmap

  • Bhutan and China signed an MoU in October 2021 establishing a Three-Step Roadmap to accelerate boundary negotiations.

2023 Cooperation Agreement

  • During the 25th round of Bhutan-China Boundary Talks in October 2023, the two sides signed a cooperation agreement establishing the functions of a Joint Technical Team on delimitation and demarcation.

Latest Developments

  • The 15th Expert Group Meeting on Bhutan-China Boundary Issues was held in Beijing from 30 March to 1 April 2026.
  • Both sides discussed implementation of the Three-Step Roadmap.
  • A Joint Technical Team also discussed boundary alignment in areas where there is no dispute.

Why Bhutan–China Negotiations Matter to India

  • India supports Bhutan’s sovereignty and its right to negotiate its own boundary settlement.
  • However, India remains particularly sensitive to any settlement affecting:
    • Doklam
    • India-Bhutan-China tri-junction
    • Chumbi Valley
    • Siliguri Corridor.
  • Therefore, India must maintain close strategic consultation with Bhutan without appearing to interfere in its independent foreign policy.

Sakteng Wildlife Sanctuary Issue

  • In 2020, China raised objections regarding funding for Bhutan’s Sakteng Wildlife Sanctuary at a Global Environment Facility meeting.
  • Bhutan strongly rejected China’s claim and stated that Sakteng is an integral and sovereign part of Bhutan.
  • The episode demonstrated the expanding geographical scope of Bhutan-China territorial differences.

Significance of Bhutan’s Stability for Northeast India

  • Bhutan shares borders with:
    • Assam
    • Arunachal Pradesh
    • West Bengal
    • Sikkim.
