The China-Europe Railway Express, or China Railway Express (CRE), is key logistical cog in President Xi Jinping’s Belt and Road Initiative. It provides an alternative to container shipping for transporting Chinese manufactured goods to Europe via Russia.

In 2022, Russian Railways was forced to respond promptly to the changes. During the year, loading in the direction of unfriendly countries fell by 37%, in the direction of friendly countries — increased by 23%, including by 28% — to China. This increased the demand for the Eastern Polygon.
