The Belt and Road Initiative promotes the development of cities along the route，and also promotes the pace of China’s related industries of “going out”. China’s urban railway system industry is ushered in an outbreak period. Guangzhou Metro Group undertakes the operation service of Pakistan Lahore Orange Line，thus becoming one of the benchmark projects of Guangzhou’s railway system to “going-out”. Through the Lahore Orange Line project，Guangzhou Metro Group has gained valuable cross-border operation experience. For example，the business objectives for external expansion should be clarified，and the importance of coordinated development should be recognized so as to realize “three connections” in terms of the manner of working. Also，communication with local embassies and consulates should be strengthened，and the brand image of the Group in the Belt and Road market should be better. Looking forward to the future，Guangzhou Metro Group，based on Guangzhou，representing China，is committed to serving the Belt and Road Initiative，driving the railway system industry chain to go global together，and constructing a new development paradigm of service featuring both domestic and international circulations with practical actions.
