Marine transportation is the most important mode of transportation in international trade, and more than two-thirds of the total international trade volume. Most of China's import and export goods are transported by marine transportation. The advantages of ocean transportation are its large volume, low shipping cost, and easy access to waterways.
However, its slow speed, high sailing risks, and inaccurate sailing dates are its disadvantages. According to the operation mode of ships, marine transportation can be divided into liner shipping and charter shipping; according to the classification of regions, container shipping can be divided into domestic shipping and foreign trade shipping.
