In 1961 China established a state-run maritime shipping company and subsequently signed shipping agreements with many countries, laying the foundation for developing the country's ocean transport. That organization developed into the present-day China Ocean Shipping (Group) Company (COSCO), one of the world's largest shipping corporations. The Chinese government also invested heavily in water transport infrastructure, constructing new ports and rebuilding and enlarging older facilities.

A major effort has also been made to increase mechanization and containerization at major international ports. In addition, China has become one of the world's premier shipbuilding countries, satisfying domestic demand and exporting ships and oil-drilling platforms worldwide. China's shipping industry and container transportation has reached international standards both in handling efficiency and building networks.

The throughput of cargo and containers at China's ports has been the largest in the world for the past five years, with an annual growth rate of 35%.
