China's Three Gorges project celebrates its 20th anniversary on December 14 with a record-high throughput of its five-tier ship lock.

The throughput of 2014 is expected to reach a record 110 million tons, and the total throughput has reached 700 million tons.

The Three Gorges project is a multi-functional water control system. It generates electricity, controls floods by storing excess water and helps regulate the river's shipping capacity.
