China–Bhutan Relations

China–Bhutan relations are unique in contemporary international affairs: the two countries share a substantial land border but have no formal diplomatic relations, no resident embassies, and no direct trade or transportation links. Bhutan is one of the very few countries in the world that does not maintain diplomatic ties with the People's Republic of China. The bilateral relationship is dominated almost entirely by an unresolved border dispute, which has been the subject of 24 rounds of negotiations since 1984 without reaching a final agreement.^[1]

The absence of China-Bhutan diplomatic relations must be understood in the context of Bhutan's special relationship with India and the broader geopolitical competition between India and China in the Himalayan region. India has historically been the dominant influence on Bhutan's foreign policy, and the establishment of formal Bhutan-China relations would have profound implications for the regional balance of power.

Historical Background

Bhutan's historical relationship with China was mediated primarily through Tibet. For centuries, Bhutan maintained complex religious, cultural, and political ties with Tibetan monasteries, lamas, and political authorities. Bhutan's state religion, Drukpa Kagyu Buddhism, traces its origins to Tibetan Buddhist traditions, and the Tibetan and Bhutanese cultural spheres overlapped significantly, particularly in northern Bhutan.

Prior to the twentieth century, China claimed suzerainty over Tibet but exercised limited practical control. Bhutan's interactions with the Chinese imperial court were rare and largely ceremonial. The relationship was fundamentally altered by China's military annexation of Tibet in 1950-1951, which brought the People's Liberation Army (PLA) to Bhutan's northern border for the first time. The 1959 Tibetan uprising and the flight of the Dalai Lama to India further destabilised the region and prompted Bhutan to strengthen its ties with India as a counterweight to the Chinese military presence.

The 1962 Sino-Indian War, fought in part along border areas adjacent to Bhutan, confirmed the Himalayan frontier as a zone of strategic confrontation. In this context, Bhutan aligned itself firmly with India, hosting the Indian Military Training Team (IMTRAT) from 1962 onward and accepting Indian security guarantees.

The Border Dispute

The China-Bhutan border runs approximately 477 kilometres along the crest of the Himalayas. The border has never been formally demarcated, and several areas are claimed by both sides. The disputed territories can be grouped into three main sectors:

Western Sector (Doklam and Surrounding Areas)

The western sector includes the Doklam plateau (known as Donglang in Chinese), located near the tri-junction where the borders of Bhutan, China, and India meet. This is the most strategically sensitive of the disputed areas because of its proximity to the Chumbi Valley — a narrow corridor of Chinese-controlled territory that extends southward between Bhutan and Sikkim — and to the Siliguri Corridor, the narrow strip of Indian territory connecting northeastern India to the rest of the country. China claims approximately 269 square kilometres in this sector.

Central Sector

The central sector includes disputed areas in the Jakarlung and Pasamlung valleys, located north of Bhutan's Wangdue Phodrang and Bumthang districts. These are remote, sparsely populated alpine areas with limited strategic infrastructure. China claims approximately 495 square kilometres in this sector, while Bhutan disputes the Chinese claim.

Northern Sector

Additional areas of dispute exist along the northern border in the high-altitude zones. The total area of disputed territory is estimated at approximately 764 square kilometres, though estimates vary depending on the source.

Eastern Sector — The Sakteng Claim (2020)

In June 2020, China introduced a new territorial claim in the eastern sector of the border, near the Sakteng Wildlife Sanctuary in eastern Bhutan. The claim was raised at a Global Environment Facility (GEF) Council meeting when the Chinese delegation objected to a grant earmarked for the sanctuary on the grounds that the area was disputed. The claim had not formed part of any previous round of boundary negotiations and alarmed Bhutanese officials and outside observers, who interpreted it as either an expansion of Chinese territorial ambitions or a negotiating tactic to broaden the eventual scope of any settlement.^[4]

Bhutan formally rejected the claim, stating that Sakteng had never been a subject of bilateral discussion. Indian commentators viewed the move as evidence of growing Chinese assertiveness toward Bhutan, while Chinese officials maintained that the dispute had always existed but had simply not been raised previously.

Boundary Negotiations

China and Bhutan began formal boundary talks in 1984, establishing a framework for direct bilateral negotiations on the border issue. A significant milestone was achieved in 1988 when the two sides agreed to a set of guiding principles for the settlement of the boundary question, including the maintenance of peace and tranquility on the border and the resolution of disputes through peaceful negotiation.

Since 1984, 24 rounds of formal boundary negotiations have been held, alternating between Beijing and Thimphu. In 1998, the two sides signed the Agreement on the Maintenance of Peace and Tranquility along the Bhutan-China Border Areas, which committed both sides to maintaining the status quo along the border and refraining from unilateral actions that could alter the situation on the ground.^[2]

Progress has been slow. In the early 2000s, there were reports that China offered a "package deal" in which it would cede its claims in the strategically important western sector (including Doklam) in exchange for Bhutan conceding the less strategically significant areas in the central sector (Jakarlung and Pasamlung). Bhutan reportedly did not accept this proposal, in part because the affected areas in the central sector have cultural and economic significance for local communities.

In October 2021, China and Bhutan signed a Memorandum of Understanding on a Three-Step Roadmap for Expediting the Bhutan-China Boundary Negotiations, signalling renewed impetus to resolve the dispute. The roadmap envisioned an accelerated negotiation process with defined stages, though details of the agreement have not been fully disclosed.^[3]

The 2017 Doklam Standoff

The most dramatic episode in recent China-Bhutan relations was the Doklam standoff of June-August 2017. The crisis began when Chinese military engineers began constructing a road on the Doklam plateau, which Bhutan claims as its sovereign territory. India intervened militarily, deploying troops to block the Chinese road construction on the grounds that it altered the status quo in a strategically sensitive area near the India-Bhutan-China tri-junction.

The standoff lasted 73 days and brought India and China to the brink of armed confrontation. Bhutan issued a formal protest against the Chinese road construction, stating that it was a violation of existing agreements. The crisis was eventually resolved through diplomatic channels, with China halting the road construction and India withdrawing its troops. However, satellite imagery subsequently revealed that China had continued to build military infrastructure in the broader Doklam area in the months and years following the standoff.^[1]

The Doklam crisis highlighted the fundamental tripartite dynamic that shapes China-Bhutan relations: any development in the bilateral China-Bhutan relationship has implications for India, and India has both the motivation and the capability to intervene to prevent outcomes it perceives as threatening to its strategic interests.

Prospects for Diplomatic Relations

The establishment of formal diplomatic relations between China and Bhutan has been a subject of periodic speculation but has not materialized. Several factors constrain this possibility. India is deeply wary of Chinese diplomatic engagement with Bhutan, viewing it as a potential avenue for Chinese strategic influence on India's northern frontier. Bhutan itself has been cautious, recognising that establishing relations with China without Indian acquiescence could jeopardize its most important bilateral relationship.

At the same time, there are potential benefits for Bhutan in normalizing relations with China. A border settlement would provide long-term security and legal certainty. Economic ties with the world's second-largest economy could contribute to Bhutan's development and reduce its overwhelming dependence on India. Diplomatic relations with China would also enhance Bhutan's international standing and foreign policy flexibility.

The resolution of the border dispute remains the essential precondition for any normalisation of China-Bhutan relations. The 2021 three-step roadmap suggests that both sides see value in moving towards a settlement, but the geopolitical complexities — particularly the India factor — ensure that progress will be slow and carefully calibrated.
