Photo taken on April 9, 2020 shows the Dar es Salaam Port undergoing upgrading of port berths 1 to 7 in Dar es Salaam, Tanzania. The upgrade of Tanzania's largest Dar es Salaam Port, launched in July 2017, is undertaken by China Harbour Engineering Company (CHEC). The upgrade will enable large vessels with a load carrying capacity of up to 70,000 tonnes to dock at the port, while currently the port accommodates vessels with a capacity of under 30,000 tonnes. The year 2020 has been a tough one for world economies amid a global COVID-19 pandemic. Against this backdrop, China has seen resilient cooperation with the Belt and Road (B&R) countries. As the coronavirus pandemic severely hits international transport, the China-Europe freight trains play a pivotal role in land transport among countries, as shown by the rising number of trains, opening of new routes, and the volume of goods. Major B&R projects, including the China-Laos railway, China-Thailand railway, Jakarta-Bandung High-Speed Railway, and Hungary-Serbia railway are making positive headway. China's aid to Belt and Road partner countries and the experience it shared with them during the COVID-19 pandemic are valuable and render the Health Silk Road more concrete. (Xinhua)
