The Suez Canal was also continually expanded and its time-saving role in Asia-Europe trade was highlighted. At the beginning of the Maritime Silk Road are the major Chinese ports in Shanghai, Shenzhen and Ningbo-Zhoushan. The Chinese investments in Africa will connect large areas of Central and East Africa to the maritime Silk Road and thus to China and directly to southern Europe via the Suez Canal. The increasing importance of the Mediterranean as a trading center with its direct, fast connections to Central and Eastern Europe is evident from the international investments in port cities of Piraeus and Trieste. On the maritime Silk Road, on which more than half of all containers in the world are already on the move, deep-water ports are being expanded, logistics hubs are being built and new transport routes such as railways and roads in the hinterland are being created.
