HOHHOT — The Chinese land port of Manzhouli on the China-Russia border handled 4,235 China-Europe freight trains in 2021, up 18 percent year-on-year, said the local railway authorities.

Last year, the port in North China's Inner Mongolia autonomous region logged 2,235 inbound China-Europe freight trains, a 25.6 percent increase compared with the same period in 2020, and 2,000 outbound China-Europe freight trains, up 10.7 percent year-on-year.

It was the port's first time to see more inbound than outbound China-Europe freight trains.

Manzhouli, China's largest land port, has launched a series of measures including strict COVID-19 prevention and control requirements and improved local clearance efficiency so as to guarantee the smooth operation of the freight trains.

China put into operation the China-Europe freight train service in 2011, which has since served as a crucial link for trade and economic cooperation across the Eurasian continent.
