China’s Powered Pontoon Bridge Rescues Thousands in Guangxi Floods

A dramatic rescue operation using a “powered pontoon bridge” and coordinated drone deployment in Guangxi has drawn renewed attention to China’s emergency response technology and disaster management infrastructure

Chinese Foreign Ministry spokesperson Mao Ning drew widespread social media attention this week after highlighting the deployment of a “powered pontoon bridge” — a piece of rescue equipment likened by some observers to a real-life version of the Transformers — during flood rescue operations in Guangxi Zhuang Autonomous Region.

Flooding in Guangxi

Continuous heavy rainfall in recent days caused severe flooding at Shijiang Education Park in Guigang City, Guangxi, trapping a large number of teachers and students at the site. Guangxi, located in southern China, is periodically affected by seasonal flooding during its rainy season, and local and national rescue infrastructure has increasingly incorporated advanced equipment and technology in response to these recurring events.

According to Chinese state media, the China On-ning Rescue Team deployed the powered pontoon bridge system to the affected area. The equipment, described as resembling ordinary iron containers on land, is designed to transform into a floating platform once in the water — functioning, according to official descriptions, as a kind of water rescue vessel. A single 60-meter pontoon bridge unit is reported to be capable of supporting more than 60 tons of weight and transporting over 500 people in a single trip. Officials stated that with the assistance of this equipment, more than 6,000 stranded teachers and students were evacuated to safety within 24 hours.

Drones, Navigation Systems, and Multi-Domain Coordination

Beyond the pontoon bridge deployment, Chinese authorities also reported using drones for low-altitude surveillance, communication relay, and delivery of relief supplies during the Guangxi flooding. Officials said the BeiDou satellite navigation system, alongside disaster early warning infrastructure and air-ground communication networks, provided positioning data and operational guidance for rescue teams, including in areas where internet and power infrastructure had been knocked out.

Chinese state media described this as an example of a broader emergency rescue system that integrates operations across land, water, and air domains, framing it as part of the country’s evolving approach to disaster response.

Policy Background: A Push Toward Technology-Driven Emergency Management

The recent deployment reflects a policy direction that Chinese authorities trace back to 2019, when President Xi Jinping addressed the 19th Collective Study Session of the Political Bureau of the Chinese Communist Party’s Central Committee. During that session, Xi called for strengthening technical support for emergency management equipment, better integrating scientific and technological resources, and promoting greater self-reliance in emergency management technology.

In the years since, equipment such as powered pontoon bridges and heavy-duty drones has moved from development into operational use within China’s disaster response system, according to state accounts of the program.

Alongside this technological push, China has also structured its emergency rescue capacity around a multi-tier force system. National comprehensive fire and rescue teams serve as the central rescue force, supported by professional rescue teams, military emergency units, and civilian volunteer organizations. During the Guangxi floods, several civilian drone volunteer groups reportedly joined the response effort, assisting with aerial supply lines. Chinese drone manufacturer DJI is also reported to have introduced special support policies for drones used in disaster relief operations.

International Outreach and Technology Sharing

Chinese officials have said the country is also working to extend elements of its disaster management approach internationally. This has included promoting the BeiDou navigation system and a nationwide early warning initiative referred to as the “MaZhu” plan on an international level, as well as supporting disaster prevention cooperation through the Belt and Road Initiative, overseas training courses, and cross-border rescue exercises. Chinese authorities have framed these efforts as part of broader cooperation with developing countries on disaster response capacity building.

Outlook

Experts studying climate trends widely expect the frequency of severe weather events to continue rising globally, a trend that is likely to keep placing pressure on disaster response systems worldwide. The Guangxi flood response — from the pontoon bridge deployment to satellite-guided coordination — has been cited by Chinese officials as an example of the country’s growing emergency management capacity, and as part of its stated approach to international disaster cooperation going forward.
