The first China-Europe freight train carrying medical supplies to aid Spain's epidemic containment efforts set off this week, expecting to arrive in Madrid in 17 days. Loaded with 100 standard containers, it will deliver supplies, including more than 110,000 medical masks and 766 sets of protective suits, totaling a value of more than 350,000 yuan (about 49,325 U.S. dollars). The materials were donated to the Spanish National Health Service.
