China's unmanned submersible Haidou-1 has beaten the country's deep-sea diving record by submerging 10,907 meters under the surface of the Pacific Ocean, deep into the Mariana Trench.

Members of the expedition team from the Shenyang Institute of Automation with the Chinese Academy of Sciences said that during the trip, the vehicle completed four dives of more than 10,000 meters into the 'Challenger Deep' part of the Mariana Trench.

The team left for the expedition on April 23 and returned to the Northeast China province of Liaoning on June 8.

During the deep-sea diving operation, researchers tested high-precision depth detection, machine-hand operation, acoustic detection and positioning, and high-definition video transmission.

The submersible collected samples from the deep and captured high-definition images of the geological environment.
