The Government of Mongolia discussed and approved the draft intergovernmental agreement with China on jointly constructing a second 1,435-mm gauge railway line at the Zamiin-Uud–Erenhot Border Crossing during its session on March 11, 2026. The Cabinet also decided to issue a prime ministerial order authorizing the signing of the agreement.

The two sides have gradually increased the capacity for train crossings at the border point. However, the volume of cross-border freight transport has now reached the full capacity of the two border stations, limiting further growth in transportation.

As of 2025, an average of 16 broad-gauge trains and 7.5 standard-gauge trains are exchanged daily through the Zamiin-Uud–Erenhot railway border crossing, handling a total of 15.5 million tons of cargo.

According to the Media and Public Relations Department of the Government of Mongolia, further expansion of the border crossing’s capacity will require the construction of a second cross-border standard-gauge railway connection, as well as the expansion of Zamiin-Uud Railway Station, the standard-gauge railway line, and cargo transshipment facilities.
