The operator of Mongolia’s Oyu Tolgoi copper mine reported Thursday that exports of copper concentrate to China have fallen by about 70% over the past two weeks because of restrictions at a border crossing, raising concerns over potential revenue losses and disruptions to the country’s mineral sector.

The export cuts amount to a decline of about $300 million compared to normal operations and could reach $1.2 billion if restrictions continue through the end of the year, according to local media reports. Oyu Tolgoi did not confirm those loss figures in a statement to The Associated Press.

Mongolia is a major supplier of coal and copper to China, the world’s largest consumer of both commodities. China’s Ganqimaodu Border Port is adjacent to Mongolia’s Gashuunsukhait Border Port.

Mongolian border officials said the slowdown is related to infrastructure and technology upgrades at the Chinese port. In August, Chinese authorities introduced an in-vehicle facial recognition system for truck drivers, and installation and maintenance work have affected processing capacity. The Mongolian government said the Chinese embassy in Ulaanbaatar informed it that the work may continue until the end of December; Mongolian news reports said it was originally due to end by late September.

Road and Transport Minister Delgersaikhan Borkhuu said all transport routes on the Mongolian side remain open and the government was not aware of any political reasons behind the restrictions.

Finance Minister Mendsaikhan Zagdjav said some ministers were instructed during a cabinet meeting to visit the border crossing and meet with Chinese authorities, according to local news reports.

The restrictions have also affected coal exports through Gashuunsukhait, with vehicle crossings falling from 1,300 to just over 1,000 a day, border authorities said.

Mongolia’s economy relies heavily on mining, which accounts for roughly a quarter of GDP. Last year, coal and copper concentrates made up 82.3% of merchandise exports, with 89.4% of total exports going to China. Mongolia is particularly sensitive to disruptions to cross-border trade and fluctuations in commodity prices.

Analysis

Why This Matters

  • The disruption threatens a key revenue stream for Mongolia, amplifying its economic vulnerability.
  • China's reliance on Mongolia for copper and coking coal means prolonged restrictions could affect global commodity supply.
  • The situation highlights the risks of cross-border infrastructure upgrades and dependency on a single trading partner.

Background

Mongolia’s mining sector is the backbone of its economy. Oyu Tolgoi is one of the world’s largest copper-gold mines, operated by Oyu Tolgoi LLC. China is Mongolia’s overwhelmingly dominant export market, with more than 89% of exports going there. The border restrictions come amid broader infrastructure modernisation by Chinese authorities.

Key Perspectives

  • Oyu Tolgoi LLC: reported a 70% drop in copper concentrate exports and a reduction in truck convoys from 12-13 to four per day.
  • Mongolian border officials: attributed the slowdown to infrastructure and technology upgrades at China’s Ganqimaodu port, including a new facial recognition system.
  • Mongolian government: said the Chinese embassy informed it that the upgrade work may continue until December.
  • Finance Minister Mendsaikhan Zagdjav: said ministers were instructed to visit the border crossing and meet Chinese authorities.
  • Road and Transport Minister Delgersaikhan Borkhuu: said all Mongolian-side routes remain open and the government is not aware of any political reasons.
  • Chinese Inner Mongolia authorities: did not respond to inquiries from the AP.

What to Watch

  • Whether the border restrictions are extended beyond December, as feared.
  • Impact on global copper prices given Mongolia's supply role.
  • Diplomatic engagement between Mongolian and Chinese officials over the crossing.
