Karamperidis says that, for container ships with a capacity much higher than 25,000 TEUs to become viable, the economics of operating them would have to change. The Suez Canal will probably always act as a bottleneck for ships travelling from Asia to Europe but it"s not impossible to imagine a 30,000 TEU vessel or similar one day traversing a route from China to, for example, a booming African port, says Karamperidis.
