Bhutan–China Border Negotiations

The Bhutan–China border negotiations are an ongoing series of diplomatic discussions between the Kingdom of Bhutan and the People’s Republic of China aimed at resolving their undemarcated 477-kilometre shared border. The two countries have never formally delimited their boundary, and competing territorial claims — particularly over the strategically important areas of Doklam, Jakarlung, and Pasamlung — have made the negotiations a matter of intense regional interest. The talks are closely watched by India, which considers Bhutan’s western border with China as directly relevant to its own security along the Siliguri Corridor.^[1]

Formal negotiations commenced in 1984, making this one of the longest-running bilateral boundary processes in Asia. Over the course of more than four decades and 24 rounds of official talks, the two sides have developed procedural frameworks — including the 1988 Guiding Principles and the 2021 Three-Step Roadmap — without arriving at a final settlement. The border question is inseparable from the broader geopolitics of the India–China rivalry in the Himalayas, and any eventual resolution will carry significant implications for Bhutan’s sovereignty, India’s strategic posture, and the balance of power in South Asia.^[2]

Despite the absence of formal diplomatic relations between Thimphu and Beijing — Bhutan remains one of the few countries in the world without an embassy in China or vice versa — the border talks represent the principal channel of direct engagement between the two governments.

Historical Background

Bhutan and China (through Tibet) have shared a frontier for centuries, but the boundary was never formally surveyed or demarcated during the pre-modern period. During the era of the Zhabdrung Ngawang Namgyal and his successors, Bhutan’s northern territories were defined more by the practical reach of administrative authority and pastoral usage than by cartographic precision. After the People’s Republic of China absorbed Tibet in the 1950s, the question of where exactly Bhutan ended and China began became a matter of modern state-to-state diplomacy for the first time.

China’s initial position, articulated in the 1960s and 1970s, claimed approximately 764 square kilometres of Bhutanese territory across multiple sectors. Bhutanese counterclaims identified areas in the north and northwest where Chinese activities had encroached on what Thimphu considered its sovereign territory. The absence of diplomatic relations and the political sensitivities involved — Bhutan’s foreign policy was, until the Indo-Bhutan Friendship Treaty of 2007, formally guided by India — delayed the start of direct negotiations until the mid-1980s.^[1]

The Negotiation Process

Commencement and Early Rounds (1984–1996)

Direct bilateral negotiations began in 1984, when Chinese and Bhutanese officials met for the first formal round of border talks. These early sessions focused on exchanging maps, establishing areas of agreement and disagreement, and building a procedural framework for sustained engagement. Between 1984 and 1996, the two sides held multiple rounds of discussions at the vice-ministerial level, alternating between Thimphu and Beijing.

A critical milestone came in 1988, when the two governments signed an agreement on Guiding Principles for the Settlement of the Boundary. This document established that the border question should be resolved through peaceful and friendly consultations, that neither side should take unilateral action to alter the status quo, and that the final settlement should respect the interests of both countries. The Guiding Principles also affirmed the principle of maintaining “peace and tranquillity” in the border areas pending a final agreement — a formulation borrowed from the India–China border management framework.^[2]

The Package Deal Proposal

In 1996, China put forward a “package deal” proposal that would have resolved the dispute through a territorial swap. Under this framework, China would cede its claims over the disputed areas in the north — Jakarlung and Pasamlung, totalling approximately 495 square kilometres — in exchange for Bhutan’s concession of the Doklam plateau and adjacent areas in the west, totalling approximately 269 square kilometres. While the arithmetic appeared to favour Bhutan in terms of total area, the strategic significance of Doklam — located at the tri-junction of Bhutan, China, and India — made the proposal deeply controversial. India viewed any Chinese presence in Doklam as a direct threat to its narrow Siliguri Corridor, which connects the Indian northeast to the rest of the country.^[1]

Later Rounds and the Three-Step Roadmap (2016–2024)

The 24th round of border talks was held in 2016, after which the formal negotiation process entered a prolonged hiatus. In 2017, the Doklam standoff — a 73-day military confrontation between Indian and Chinese forces on the Doklam plateau, in territory claimed by Bhutan — dramatically illustrated the stakes of the unresolved border. Bhutan protested Chinese road construction in the disputed area, and India intervened militarily on Bhutan’s behalf, leading to the most serious India–China military crisis in decades.

In October 2021, Bhutan and China signed a Three-Step Roadmap for expediting the boundary negotiations. The roadmap outlined a phased approach: first, agreeing on the boundary in “less complicated” areas; second, reaching agreement on the remaining disputed sectors; and third, conducting joint field surveys and demarcating the boundary on the ground. The signing of the roadmap was seen as a significant step forward, though analysts noted that the most difficult issues — particularly the status of Doklam — were deferred to the later stages.^[2]

Disputed Areas

The border dispute centres on three principal areas:

Doklam (western sector): A plateau of approximately 89 square kilometres at the tri-junction of Bhutan, China, and India. Doklam is strategically significant because of its proximity to India’s Siliguri Corridor and the Chumbi Valley. China claims it as part of its Yadong County in Tibet.
Jakarlung (northern sector): A high-altitude area of approximately 340 square kilometres in northern Bhutan, used historically for yak herding. China claims the area based on traditional Tibetan pastoral usage.
Pasamlung (northern sector): An area of approximately 155 square kilometres, also in northern Bhutan, adjacent to Jakarlung. Together with Jakarlung, this constitutes the bulk of the northern disputed territory.

In 2020, satellite imagery and investigative reporting revealed that China had constructed a settlement and road infrastructure in the Beyul Khenpajong area of northern Bhutan, an area not previously identified as part of the formal dispute. This development raised concerns that China was expanding its territorial claims beyond the areas under negotiation, a charge Beijing denied.^[1]

India’s Strategic Interest

India’s role in the Bhutan–China border negotiations is central, though technically India is not a party to the bilateral talks. Under the Indo-Bhutan Friendship Treaty, India and Bhutan maintain a “special relationship” in which they consult closely on matters of mutual interest. India regards the Doklam area as essential to the defence of the Siliguri Corridor — a narrow strip of Indian territory, sometimes called the “Chicken’s Neck,” that connects the Indian northeast to the rest of the country. Any Chinese control of the Doklam heights would, in India’s assessment, place this corridor under strategic threat.

India has historically encouraged Bhutan not to accept the Chinese package deal, and the 2017 Doklam standoff demonstrated India’s willingness to use military force to prevent unilateral Chinese advances in the area. At the same time, Bhutan’s desire for full sovereignty over its foreign policy — formally achieved with the 2007 treaty revision — has led to a complex diplomatic balancing act in which Thimphu must weigh its security dependence on India against the potential benefits of a boundary settlement and normalised relations with China.^[2]

Recent Developments

Since the signing of the Three-Step Roadmap in 2021, Bhutan and China have held multiple rounds of expert-level discussions on boundary delimitation. In 2023, Bhutanese Foreign Minister Tandi Dorji and Chinese counterparts met on the sidelines of international forums, signalling continued diplomatic momentum. Reports have suggested that the two sides may be close to agreement on the northern sector (Jakarlung and Pasamlung), with the more sensitive western sector (Doklam) to be addressed subsequently.

The potential establishment of formal diplomatic relations between Bhutan and China — Bhutan is one of the last countries in the world without such ties to Beijing — has been linked to progress on the boundary question. Any normalisation of relations would mark a historic shift in Bhutanese foreign policy and would inevitably be viewed through the lens of the broader India–China strategic competition in the Himalayan region.
