China's unmanned underwater vehicle Haidou dived to a depth of 10,767 meters, setting a new record for the country in the Mariana Trench in the West Pacific, the deepest area in the world, during a scientific expedition from June 22 to Aug. 12, 2016. 

During the mission, the submersible dived over 8,000 meters below the sea surface once, 9,000 meters twice, and 10,000 meters twice. This makes China the third country after Japan and the United States to have built unmanned underwater vehicle capable of reaching depths in excess of 10,000 meters.
