China State Shipbuilding Corporation (CSSC) delivered the world's largest dual-fuel container ship with a capacity of 24,000 TEUs (twenty-foot equivalent units) in Shanghai on Tuesday. The vessel will be deployed on the Far East to Europe shipping route.
Nicknamed "Super Cargo King of the Sea," the newly delivered ship is capable of carrying 220,000 tons of cargo, with its 24,000 containers stacked as high as a 25-story building. The ship is powered by liquefied natural gas (LNG), and the green fuel could sustain a cruising range of nearly 20,000 nautical miles on a single voyage.
"This ship is the most advanced in the world. Its key feature is that it's powered by liquefied natural gas, which is cleaner and more environment friendly. And its container capacity is the largest in the world, significantly enhancing the shipping efficiency and economic viability," said Wang Jiaying, head of marketing at Hudong-Zhonghua Shipbuilding, a subsidiary of CSSC.
China has kept setting new records in container ship construction, with capacities increasing from 21,000 TEUs to 23,000 TEUs, and now to 24,000 TEUs. While the ships are getting larger, their construction time has become shorter, demonstrating China's shipbuilding capabilities.
"We have made some breakthroughs in shipbuilding through technological renovation. From the start of construction to the ship's launch at the dock, the cycle has been shortened to just four to five months. Compared with previous construction cycles, this is a significant improvement. In fact, the delivery of this ship was more than six months ahead of schedule. Our control over the construction cycle is now at a first-class level in the global shipbuilding industry," said Liu Xuedong, vice president of Changxing Shipbuilding at Hudong-Zhonghua Shipbuilding.

From cutting-edge technology exhibitions to retail stores thousands of kilometers away from Europe and Southeast Asia, China-made robot vacuum cleaners are increasingly becoming a popular choice among consumers worldwide.
At electronics retailers in Berlin, Germany, Chinese brands such as Roborock and Dreame occupy prominent positions in dedicated robot vacuum sections, offering a wide range of products priced between 200 and 2,000 euros.
Many local consumers said that when purchasing smart home appliances including robot vacuum cleaners, they tend to give priority to Chinese-made products.
"It's a good price and good quality. It's also the innovation. I have a feeling that the European brands are not innovating enough," said one customer.
"I think they're always on top of the other technologies. They are getting them out faster. A lot of us are switching to the Chinese technology," another consumer said.
Germany is one of the most important overseas markets for China's floor-cleaning robots.
According to data from market research firm GfK, from January to November 2025, more than six out of 10 robot vacuum cleaners sold in Western Europe were Chinese brands.
Industry data also point to a strong global momentum.
According to the International Data Corporation (IDC), global shipments of smart robot vacuum cleaners reached 17.424 million units in the first three quarters of 2025, representing a year-on-year increase of 18.7 percent.
Chinese brands including Roborock, Ecovacs, Dreame, Xiaomi and Narwal ranked among the world's top five in terms of shipment volume, with a combined share of nearly 70 percent of the global market.
At a robot vacuum cleaner manufacturing plant in Huizhou, south China's Guangdong Province, workers were seen stepping up production of newly launched models that recently debuted at the Consumer Electronics Show in the United States, which concluded Friday in Las Vegas, Nevada.
The factory adjusted its production lines as early as December 2025 and stocked inventory in advance for overseas markets to ensure that new products could be delivered to global consumers at the earliest possible time.
"In 2025, Roborock's global shipments exceeded 7.2 million units. Since 2024, overseas revenue has accounted for more than 50 percent of our total revenue. Our products have now been sold to more than 170 countries and regions, serving more than 20 million households worldwide," said Quan Gang, president of Roborock.
At another robot vacuum cleaner manufacturing facility in Dongguan, Guangdong, rising overseas orders have prompted the company to upgrade its production lines with intelligent technologies to further boost capacity. The factory is currently operating at full load to meet a growing demand.
"For 2026, we have already obtained overseas orders worth at least 300 million to 400 million yuan (around 43 million to 57.3 million U.S. dollars). In addition, we've engaged in strategic cooperation with European home appliance group Cebos Group, and our total confirmed orders have exceeded 600 million yuan (around 86 million U.S. dollars)," said Zhang Junbin, founder and CEO of Narwal Robotics.
