There is a Chinese saying that is universally applicable: "If you want to get rich, build roads first." The Belgrade expressway, which became operational last year, is one example of China's close cooperation with Serbia in infrastructure development. CGTN's Yang Xinmeng visited the office of a Chinese company based in Serbia to experience the daily corporate lives of local employees involved in the highway project. Yang joined a self-driving journey of speed and friendship along the Belt and Road.
