The China-Europe freight trains made a total of 1,357 trips in May, an increase of 31 percent year on year, the National Development and Reform Commission said Saturday.
These trains carried 131,000 twenty-foot equivalent unit (TEU) containers of goods last month, up 40 percent from a year earlier.
As of the end of May, approximately 40,000 trips with about 3.55 million TEU containers had been made via the intercontinental rail route.
The freight trains had reached more than 160 cities in 22 European countries, data from the commission shows.
Ning Jizhe, deputy head of the commission, stressed that China will step up efforts to coordinate the rail services with economic and trade cooperation.
More work will be done to upgrade some major customs and railway sections to improve services and infrastructure along the train route, Ning said.
