As the largest exporter of goods moving on container services, China ranks as number one in the top fifty global container ports. Furthermore, Singapore ranks as number two mainly because it is an important hub where containers from one-liner service are transferred to another liner service for on-carriage to their final destination. The top 50 containers ports represent 30 countries demonstrating the truly global nature of the liner shipping business and the importance of the network of ports that facilitate timely and efficient ship and cargo movement.
