"China is our most valued market with great potential for cooperation," said Toon Balm, general manager of Air France KLM Greater China, in an interview with People's Daily.

The Liege Airport, Belgium's largest airport in terms of cargo throughput, registered cargo volume of 1.12 million tons last year, up 24 percent on a year-on-year basis. This is largely due to the continued growth of trade between Europe and China, reported Belgian broadcaster RTBF. Protective materials and electronic components are shipped from China to Europe, helping Europe fight against the pandemic and boosting work and production resumption as well.

According to China State Railway Group, the China-Europe freight trains hit new record of 12,400 journeys in 2020, transporting 1.14 million twenty-foot equivalent unit (TEU) containers of goods, an increase of 50 and 56 percent on a yearly basis, respectively. 76,000 metric tons or 9.31 million pieces of anti-epidemic supplies were delivered via China-Europe freight trains last year, enhancing international medical cooperation to combat outbreak, and stabilizing global industrial chain.
