China has developed a deep sea mining ship, and Japan once considered asking for double the price. Deep sea mining ships are in high demand as they allow countries to exploit seabed resources. China is the first and only country to own such ships, providing a technological advantage. The construction of these ships posed challenges for China due to the lack of previous experience and the need for advanced materials. The ships are equipped with mining machines that can level the seabed, crush and collect ore, and transport it to the ship. China's strategic goal of becoming a maritime power led to the construction of the first deep sea prospecting ship, named "Nautilus New Era," but it faced obstacles such as reliance on imported equipment and materials. Despite these challenges, China overcame them and completed the construction of the ship, marking a significant achievement for its deep sea strategy and maritime power aspirations.
