Manzhouli, China's largest land port, handled more than 10 million tonnes of imports and exports in the first half of this year, up 46.1 percent year on year, marking a record high for the period, according to China Railway Harbin Bureau Group Co., Ltd.

The port in north China's Inner Mongolia Autonomous Region has seen robust growth in its traffic volume since the beginning of this year.

So far, it has handled a maximum of 28 trains in a single day, eight of which were outbound trains, said Liu Huichao, deputy head of the Manzhouli railway station.

China Railway Harbin Bureau Group Co., Ltd. said that it has taken multiple measures over the years to improve the operation and transport efficiency of the ports that it administers, which has helped the ports' freight and traffic volumes increase progressively year by year.
