ZHENGZHOU — A total of 3,000 cargo trains have been operated from the city of Zhengzhou, capital of Central China's Henan province, to cities in Europe and Asia as of April 29.

The 3,000 trains carrying a total of about 1.55 million tons of goods worth more than $12.7 billion have facilitated the province's opening up to the outside world.

Launched in July 2013, the logistic network of China-Europe freight train services originating from Zhengzhou has covered places including Europe, Central Asia, Japan, Republic of Korea and the ASEAN nations, with direct routes to seven destinations.

"Currently, the freight train services have helped offset the impact of the epidemic on China-Europe industrial chain and supply chain cooperation, serving as a green channel for European countries to timely obtain medical supplies and daily necessities," said Zhao Wenming, general manager of the Zhengzhou International Hub Development and Construction Co Ltd.
