What is the longest strait in the world?

The Strait of Malacca is the longest strait in the world. It is a funnel-shaped narrow waterway of 800 km long that connects the South China Sea and the Andaman Sea. As the link between the Indian Ocean and the South China Sea, the Strait of Malacca is the shortest sea route between India and China and hence is one of the most heavily travelled shipping channels in the world. In early times, it helped to determine the direction of major Asian migrations of peoples through the Malay Archipelago.
