Chinese design makes tracks on the Moscow metro(5)

For example, the machine named Polina worked in temperatures below-35 C last winter, successfully cutting through 1.5 km of the most different underground terrain, Liu said, adding that it broke a Russian record by excavating 35 meters of terrain in a day.

The success of Chinese companies in Russia is due to high-quality construction work, highly reliable machinery manufactured in China and conscientious Chinese workers, Kong said.

More important, good bilateral relations between China and Russia have boosted cooperation and enabled Chinese companies to gain more trust from local governments and markets, Kong added.

As the leaders of the two countries have repeatedly said, the Sino-Russian comprehensive strategic partnership of coordination for a new era propels a high level of mutual trust, and bilateral relations between Beijing and Moscow have reached the highest level in history, Kong said.

Since the pandemic emerged last year, the two governments have maintained practical cooperation and continued to support infrastructure projects.

Such projects include the cross-river railway bridge connecting Tongjiang, a city in Heilongjiang province, with the Russian town of Nizhheleninskoye, and expressway construction.

Kong said that against this advantageous backdrop, Chinese companies have received better understanding and trust in Russia.
