China-Europe railway/train links are vital for connectivity and trade in the Eurasian region. China to Europe freight trains are in operation since 2011. The sea communication lines have certain disadvantages such as time, temperature, and international political interference in the Oceans. Thus, China-Europe trade through railways is significant for China and other regional countries. Moreover, China has also backed few passenger railway lines such as China-Laos passenger train (Boten-Vientiane railway) besides passenger train connecting Hungary and Serbia in Europe called Budapest-Belgrade railway. The freight trains are connecting China with Netherlands, Germany, Spain, Italy and other countries in Europe.
