This year marks the 50th anniversary of the establishment of diplomatic relations between China and the European Union. The China-Europe Railway Express has now surpassed 110,000 trips, becoming a vital golden corridor linking Asia and Europe. The service currently reaches 229 cities across 26 European countries and over 100 cities in 11 Asian nations. It is without a doubt a key engine of Eurasian trade. CGTN's Huang Yaohui has more.
