China-Europe freight train trips via eastern corridor exceeded 6,000 as of Friday, up 40.3 percent year on year after a return train carrying timber boards departed from the Suifenhe land port in northeast China's Heilongjiang Province, bound for Zhengzhou City in central China.

It marks the first time annual traffic through the corridor exceeded 6,000 trips within a single year, setting a record for the same period in history.

The east corridor, comprising three railway ports of Manzhouli, Suifenhe and Tongjiang North, connects more than 60 cities across China and reaches 14 European countries, including Poland and Germany.
