Nepal-China Border Crossings: The Traditional Trade Points

Nepal's entire northern boundary runs along the crest of the Himalaya and separates the country from the Tibet Autonomous Region (TAR) of the People's Republic of China. The Nepal Economic Forum and Nepali government sources cite a border length of about 1,414 kilometres, while Wikipedia and some Western surveys give 1,389 km; the figures differ because of how the sinuous ridge-and-watershed line is measured. Either way it is one of the highest international frontiers on Earth, touching the summit of Mount Everest (Sagarmatha, 8,848.86 m), which the two states agreed to treat as a shared peak.

The modern boundary was fixed by a series of agreements in the early 1960s: an initial boundary agreement on 21 March 1960, the definitive China-Nepal Boundary Treaty signed on 5 October 1961, and a final boundary protocol in 1963 that demarcated the line on the ground with pillars. This settled a frontier that for centuries had been an open trans-Himalayan trading zone rather than a hard line, and it is the legal basis for every crossing described below.

This page is about the modern, operational frontier - the customs points and passes where people and goods actually cross today, covering for each which side names apply, the district and county, elevation, road access and current status. It is distinct from the historic caravan routes (the salt-for-grain trade over passes such as Nangpa La and Tipta La) that shaped Himalayan commerce for centuries, which are covered separately.

Nepal and China distinguish between a small number of designated international ports of entry and a larger set of traditional local trade points. Under the bilateral border-trade arrangements (the 2012 protocol and later reviews), six locations are recognised as the principal ports of entry open in principle to third-country nationals and formal customs trade. On the Nepal side these are administered by the Department of Customs under the Ministry of Finance, which maintains customs offices and revenue posts at the active points.

Beyond these six, both governments recognise 21 traditional trade points spread across the northern districts, historically used by border communities for local barter and seasonal exchange. Chinese authorities closed these passes in January 2020 against COVID-19, badly hurting remote Himalayan villages that depend on Tibetan salt, grain and consumer goods. On 26 May 2024, Deputy Prime Minister and Foreign Minister Narayan Kaji Shrestha and TAR Vice-Chairman Silang Nima jointly reopened 14 of the 21 traditional trade points at a ceremony in Chentang, covering communities in Taplejung, Sankhuwasabha, Dolakha, Gorkha, Mustang, Dolpa and Darchula.

Geographically the frontier is spread across roughly 15 mountain districts in five provinces: Koshi (Taplejung, Sankhuwasabha, Solukhumbu), Bagmati (Dolakha, Sindhupalchowk, Rasuwa), Gandaki (Gorkha, Manang, Mustang), Karnali (Dolpa, Mugu, Humla) and Sudurpashchim (Bajhang, Darchula). On the Chinese side the counterpart counties fall almost entirely within Shigatse Prefecture, with the far-western crossings (Hilsa, Tinkar) opening into Burang County of Ngari Prefecture.

The two crossings in Bagmati Province carry the overwhelming majority of formal Nepal-China trade because both are linked by road to Kathmandu. Rasuwagadhi in Rasuwa district, at roughly 1,850 m on the Trishuli headwaters, faces the Chinese port of Kerung (Gyirong/Jilong). Since the 2015 Gorkha earthquake it has been Nepal's principal cargo gateway, handling readymade garments, electronics, footwear, machinery and electric vehicles. Two-way trade fully resumed here from April 2023.

Tatopani in Sindhupalchowk - the customs point sits near Kodari at around 2,300 m - faces the Chinese border town of Zhangmu (Khasa) in Nyalam County. This was Nepal's historic main artery on the Araniko/Friendship Highway, once carrying well over a billion US dollars of trade a year. It was crippled by the 2015 earthquake and closed for more than eight years; two-way cargo trade restarted on 1 May 2023 and passenger movement resumed from 1 September 2023.

Both routes have proven vulnerable to Himalayan hazards. On 8 July 2025 a flash flood on the Lhende (Bhotekoshi) river swept away the Miteri friendship bridge at Rasuwagadhi-Kerung, halting the country's busiest crossing at the peak festival-import season and stranding hundreds of goods containers on the Chinese side. After China built a temporary Bailey bridge, the point came back into partial operation in late December 2025, with import-export activity resuming from 1 January 2026 - though initially only Rasuwa-district residents were allowed to cross, leaving traders from other districts frustrated.

Korala (Kora La) in Upper Mustang, Gandaki Province, has emerged as the trade story of the mid-2020s. At 4,660 m it is the highest of Nepal's motorable crossings and is often described as the lowest drivable pass between the Tibetan Plateau and the Indian subcontinent, reached via the Kaligandaki Corridor. Port facilities were built at Nechung on the Nepal side and Lektse (Lizi) on the Chinese side. It reopened for Upper Mustang residents from 13 November 2023, came into full operation for trade in August 2025, and a new immigration office at Nechung now lets Nepali, Indian and third-country pilgrims travel to Mount Kailash and Lake Mansarovar directly through Korala.

Yari, with its border settlement of Hilsa in Humla district, Karnali Province, is the far-western trade and pilgrimage gate, sitting at roughly 3,600 m on the Karnali (Humla Karnali) river and opening into the Chinese town of Purang (Taklakot/Burang) in Ngari Prefecture. Hilsa is the traditional overland approach for Kailash-Mansarovar pilgrims from western Nepal; the crossing reopened in April 2023 and its road connectivity was reported fully operational by mid-2025, though the Nepal-side road from Simikot remains rugged and weather-dependent.

These two western points matter disproportionately for religious tourism. Because both give relatively direct Tibetan-side access to the Kailash-Mansarovar circuit, their reopening has revived pilgrim traffic long diverted through Kerung and strengthened the case for all-weather roads up the Kaligandaki and Karnali corridors.

Kimathanka, in Bhotkhola rural municipality of Sankhuwasabha district, Koshi Province, is the eastern counterpart of the Chinese township of Chentang (Zhentang) in Dinggye County. Long a lifeline for local barter - a 2015 count recorded some 7,700 crossings - Kimathanka is central to the planned Biratnagar-Khandbari-Kimathanka corridor, promoted as the shortest road link between India, Nepal and China in eastern Nepal (about 362 km). It was among the 14 traditional points reopened in May 2024, and by 2026 the Nepal Army had completed the rough track road up to the border, although through-traffic and full customs handling remain works in progress.

Olangchung Gola in Phaktanglung rural municipality of Taplejung district, Koshi Province, is Nepal's easternmost designated crossing, using the historic Tipta La (also called the Walung Chung pass), a trade route to Tibet lying above 5,000 m that connects to the Chinese port of Riwu (Ri'og). China built a road up to Tiptala Bhanjyang on its side in late 2016; the Nepal-side track and a revenue post have been developed more slowly, and the point functions mainly for seasonal local trade and the culturally Tibetan Walung community.

Both eastern crossings illustrate the wider pattern of the frontier: the Chinese side is typically reached by sealed all-weather road years before the Nepal side, where access depends on long, landslide-prone tracks. Closing this infrastructure gap is the main constraint on turning traditional points into genuine trade gateways.

Alongside the six recognised ports of entry, several older passes retain historic, cultural or limited-trade significance even though they are not full customs points. The most famous is Nangpa La in Solukhumbu (around 5,800 m), the classic Sherpa trading and refugee route over to Tingri; China curtailed its official crossing status in 2006, and it is now effectively closed to formal trade. Others open only briefly each year or serve a handful of border villages.

Tinkar (Tinker) in Darchula district, Sudurpashchim Province, connects far-western Nepal to Purang/Taklakot and was among the 14 points reopened in 2024, serving the Byas valley communities. In Karnali, Marim La (Dolpa) and Nakchenangla (Mugu) are minor seasonal passes - the latter historically open only about a week a year. Ruila in Gorkha (Gandaki) and Phu in Manang are small local points, while Lapchi in Dolakha is a pilgrimage-linked crossing near a sacred Milarepa site. These points anchor community trade rather than national commerce, but their reopening restores customary access that mountain households have relied on for generations.

It is worth stressing how much status can change year to year. Nepal and China list 21 traditional trade points in total; only 14 were reactivated in 2024, and even among the six main ports, day-to-day operability shifts with monsoon damage, bridge failures, road-building progress and bilateral politics. Any traveller or trader should confirm the current status of a specific point with the Department of Customs or local administration before relying on it.

The overall trajectory since 2023 has been one of gradual reopening after the long COVID freeze, coupled with heavy Chinese and Nepali investment in connectivity under the Belt and Road Initiative (BRI) framework and Nepal's own trans-Himalayan corridor plans. Rasuwagadhi-Kerung and Tatopani-Zhangmu remain the commercial backbone; Korala has become a fast-rising alternative and pilgrimage gate; and the eastern and far-western points are being slowly upgraded from footpaths to motorable tracks.

The recurring theme is fragility. The July 2025 Lhende flood that severed the Rasuwagadhi bridge, the years of earthquake closure at Tatopani, and the seasonal impassability of high passes all show how thin the margin is on this frontier. Restrictions limiting crossing to local residents, incomplete customs facilities and asymmetric road development further blunt the trade potential that map distances suggest.

For a Nepali audience the takeaways are clear: the border is reopening but unevenly; formal trade still concentrates on the two Bagmati crossings; Korala and Hilsa are the pilgrimage-friendly western gates; and Kimathanka anchors the east's trilateral-corridor ambition. Status is best treated as provisional and checked against current customs and government notices.
