China Jiaolong dived to 667 1 m, breaking the world record. Didn't Hollywood director Cameron take a private submarine to 10000 meters and seek the scientific spectrum?

Jiaolong is an operational manned submersible, and Cameron's Deep Sea Challenger is an exploratory manned submersible, so there is no comparability between them. Jiaolong broke the diving record of the same type of submersible.

Explore manned submersibles

The diving ability is strong, and it can go deep into the seabed of 1 1 km, but the activity range is limited, so this type of submersible cannot operate flexibly. It is like a "deep-water elevator", and the observer will return after diving to the designated place. The dive time is short, and each dive can only last for 4 to 5 hours. It can't be operated and studied underwater, and it will float up soon after reaching the depth, and the number of dives is limited (only a few times), with low safety performance and lack of economic returns. Can only be used for exploration, photography, and breaking the record of deep diving. For example: Astor 2, Deep Sea Challenger.

Operational manned submersible

Countries all over the world independently develop and manufacture them for deep-sea exploration and scientific research projects. Active submersible with underwater observation and operation ability. It is mainly used for underwater exploration, seabed exploration, seabed development and salvage, lifesaving and other tasks, and can be used as an underwater operation base for divers' activities. Its diving can bring greater economic returns. It is a self-propelled submersible with long design life and can dive thousands of times. For example, Alvin in the United States, Nautilus in France, Heping No.1 and Heping No.2 in Russia, Deepwater 6500 in Japan and Jiaolong in China.
