Rotterdam, Netherlands, was the busiest port city in the world from 1962 to 2004.
It handles more than 325 million tons of cargo annually, and is situated in the Dutch province of South Holland.
In 2005 Shanghai became the world’s largest cargo port as a result of economic reforms, intense re-development, and financing in the city.
The city of Shanghai is located at the middle portion of the Chinese coast, and sits at the mouth of the Yangtze.
Once a fishing and textiles town, Shanghai is now the largest center of trade and commerce in mainland China, and is described as the “showpiece” of the world’s fastest-growing major economy.
Other busy seaports in the world include the Port of South Louisiana in New Orleans, the port of Singapore, and Kobe in Japan.
