China is building, by present standards, the world’s longest highway tunnel – a project that will traverse one of the planet’s longest mountain ranges and open new pathways for exchanges between the country’s Xinjiang Uygur autonomous region and Central Asia, which experts said is an increasingly decisive area for foreign trade.
A crucial section of the Urumqi-Yuli Expressway, the Tianshan Shengli tunnel will serve as a pivotal transport link between the southern and northern halves of the region, state media said.
When opened to traffic by the end of October 2025, it will cut travel time through the Tianshan Mountains to about 20 minutes, and the journey from capital Urumqi to Korla, the region’s two most populous cities, will be shortened from more than seven hours to about three hours.
As China builds closer diplomatic and economic ties with Central Asia, the region will be an increasingly important fulcrum as both a final market and a transit point, Xu added, with more infrastructure development likely in the works to boost connectivity, including the construction of the China-Kyrgyzstan-Uzbekistan railway.
Enhanced transport networks would strengthen Xinjiang’s broader infrastructure links with Central Asia, said Peng Peng, executive chairman of the Guangdong Society of Reform, a think tank connected to the provincial government.
“There are already numerous channels for railways, highways and aviation, while cultural exchanges such as group tourism and self-guided travel are relatively scarce. The new pathway could diversify trade methods and even extend to further cultural and tourism exchanges,” Peng said.
