China highly values marine sci-tech innovation and empowerment. It launched the Hadal Science and Technology Program, accomplishing a manned submersible diving to 10,000 meters in the Mariana Trench. A large-scale depository has been established to preserve marine microbial samples. China's deep-ocean drilling vessel Meng Xiang is poised to lend its support to advancing the International Ocean Drilling Program.

In response to the UN Ocean Decade and the International Decade of Sciences for Sustainable Development, China has co-initiated 10 Big Science Programs. It released the world's first multimodal large model for deep-sea typical habitats, marking a significant breakthrough in the integration of deep-sea science and artificial intelligence. China's manned deep- sea submersible Jiaolong and dozens of scientific research vessels, including Shenhai Yihao, are available to the international community for joint cruise, which contributes to the access to and sharing of the research outcomes.
