India and Bhutan: A Friendship Rooted in Trust and Shared Growth

Prime Minister Narendra Modi’s 2025 visit to Bhutan , coinciding with the 70th birth anniversary of His Majesty Jigme Singye Wangchuck , reaffirmed the deep and enduring partnership between the two Himalayan neighbours. Welcomed warmly by Prime Minister Tshering Tobgay in Paro, the visit underscored mutual respect, constant dialogue, and a shared vision for peace and prosperity — continuing a relationship that has evolved over seven decades of cooperation and trust.

A Legacy of Trust and Partnership

India–Bhutan relations, among the most successful in South Asia, are anchored in the Treaty of Peace and Friendship (1949) , which established close political and developmental ties shortly after India’s independence. This treaty laid the foundation for a partnership built on non-interference, consultation, and mutual respect.

To reflect Bhutan’s democratic transition and growing global engagement, the treaty was revised in 2007 , granting Thimphu full authority over its foreign policy while maintaining India’s supportive role in its development and security.

The moral foundation of this bond was symbolised by Jawaharlal Nehru’s 1958 visit , accompanied by Indira Gandhi . Travelling through Bhutan’s rugged terrain on horseback, Nehru assured the Bhutanese that India would always help preserve their independence — a pledge that has since guided bilateral relations. Over time, successive leaders have strengthened this trust, turning it into a model for regional cooperation under India’s Neighbourhood First Policy .

Strategic and Developmental Significance

Bhutan occupies a critical place in India’s strategic outlook, serving as a buffer between India and China . Its proximity to the Chumbi Valley and Doklam Plateau , near India’s Siliguri Corridor or “Chicken’s Neck” , makes it vital for India’s security. Bhutan’s alignment with India in SAARC, BIMSTEC, and BBIN enhances regional stability, while joint border management curbs cross-border movement of insurgent groups in India’s Northeast.

Economically, India remains Bhutan’s largest trading partner — accounting for over 75% of imports and 60% of exports — and the principal source of development assistance through Bhutan’s Five-Year Plans. Hydropower cooperation forms the backbone of this partnership, with joint ventures like Chukha (1988), Tala (2006), Kurichhu (2001) , and Mangdechhu (2019) contributing over 25% of Bhutan’s revenue and supplying clean electricity to India. The Indian Rupee’s convertibility with the Bhutanese Ngultrum and currency swap facilities further ensure Bhutan’s financial stability.

Expanding Areas of Cooperation

India–Bhutan cooperation extends beyond hydropower to education, health, and digital connectivity . India trains the Royal Bhutan Army , assists in border management, and has stood firmly by Bhutan’s side during key moments — most notably the 2017 Doklam standoff , when Indian troops intervened to deter Chinese construction on disputed land claimed by Bhutan. Infrastructure initiatives such as Project DANTAK (since 1961) and new rail links like Gelephu–Kokrajhar and Samtse–Banarhat are strengthening physical and economic connectivity.

Navigating Emerging Challenges

Despite warmth at the political level, both sides face evolving challenges. Bhutan’s ongoing border talks with China (since 1984) over northern and western sectors, including Doklam , hold implications for India’s security. Hydropower projects have seen cost overruns and delays , fuelling local debates about equity and dependence. Bhutan’s trade deficit with India and its aspirations for economic diversification into IT, tourism, and green industries highlight the need for a broader partnership.

Connectivity constraints and Bhutan’s hesitation over the BBIN Motor Vehicles Agreement (2015) due to environmental concerns have slowed subregional integration. A mild “Big Brother” sentiment persists among some Bhutanese voices, reflecting sensitivities about India’s dominant role. Balancing Bhutan’s Gross National Happiness model with India’s infrastructure-led approach and addressing border security issues such as smuggling and illegal crossings remain ongoing tasks.

The Way Forward

As India and Bhutan move forward in an increasingly complex regional environment, their partnership continues to stand out as a model of mutual trust, respect, and shared growth. Both nations have demonstrated that differences in size or power need not translate into imbalance when relationships are guided by sincerity and understanding. The future trajectory of India–Bhutan ties will depend on sustaining this spirit — by addressing economic asymmetries, expanding people-to-people engagement, and aligning developmental goals with environmental sustainability. As Bhutan pursues economic diversification and India strengthens its Neighbourhood First Policy , collaboration in emerging areas such as digital connectivity, green technology, education, and climate resilience will define the next chapter. Greater focus on innovation, skill development, and sustainable tourism can further deepen mutual benefits, while continuous dialogue and cultural exchange will strengthen the social fabric of the relationship. Anchored in history but oriented toward the future, the India–Bhutan relationship remains a beacon of how close neighbours can prosper together through dialogue, empathy, and a shared commitment to peace and progress.
