Four China-Europe freight trains, packed with containers of goods, set off from China's Guangdong and Hunan simultaneously for central Asia and Europe on Thursday.
The four trains, loaded with 200 containers of goods, are headed to Germany, Russia and Belarus.
They are expected to arrive in about two weeks, according to Sinotrans.
The goods carried by the trains include medical supplies to fight the COVID-19 pandemic, toys, electronic items, furniture and bicycle frames.
Since the first China-Europe freight train was launched in March 2011, the service has reached more than 160 cities in 22 European countries.
Countries along the international freight route have shown growing interests in cooperation on upgrading logistics chains to speed up post-pandemic recovery.
