China is rapidly emerging as a global power house in technologies shaping the cities of the future. Through a combination of government-backed initiatives and strategic private sector investment, Chinese companies are pioneering breakthroughs in artificial intelligence (AI), 5G networks, and electric vehicles (EVs), creating urban environments that are smarter, greener, and more sustainable.

AI transforming urban life

Artificial intelligence is at the heart of China’s urban revolution. In Hangzhou, Alibaba’s City Brain system leverages AI to monitor traffic flows, reduce congestion, and improve emergency response times. Similarly, in Shenzhen, Baidu has piloted autonomous buses integrated with real-time AI analytics, enhancing public transport efficiency and safety. These initiatives show how AI can be seamlessly woven into city management, offering tangible benefits to millions of urban residents.

5G connectivity driving innovation

China is also leading the world in 5G deployment. Telecom giants Huawei and ZTE have rolled out nationwide 5G networks, enabling applications ranging from autonomous vehicles to smart grids and industrial Internet of Things (IoT) solutions. In Shanghai, 5G-enabled traffic systems allow real-time communication between vehicles and traffic lights, helping reduce accidents and improve traffic flow. By integrating high-speed connectivity with urban infrastructure, Chinese cities are setting a benchmark for smart, connected urban living.

Electric vehicles and sustainable transport

The EV sector is another area where China is redefining global standards. Companies like BYD, NIO, and XPeng have made China the world’s largest EV market and exporter. Cities such as Shenzhen and Beijing have incorporated EV fleets into public transport, significantly reducing urban air pollution. Extensive charging infrastructure and smart mobility platforms are facilitating the rapid adoption of EVs, while also creating new opportunities in battery innovation and renewable energy integration.

Green city initiatives

China’s green city projects exemplify the integration of multiple advanced technologies. Hangzhou has implemented AI-driven energy grids and smart water management systems, while Shenzhen uses solar-powered bus depots and IoT-based waste management solutions. These initiatives demonstrate how AI, renewable energy, 5G, and EV infrastructure can work together to create sustainable, efficient urban ecosystems.

Lessons for Bangladesh

Bangladesh, facing rapid urban growth and mounting environmental challenges, can draw key lessons from China’s approach to building smarter, greener cities. Artificial intelligence can play a central role in urban management, with traffic monitoring systems, smart energy grids, and predictive analytics helping cities like Dhaka and Chattogram reduce congestion and optimise resource use.

Electrifying transport is another critical step. By promoting local EV production, expanding charging infrastructure, and integrating electric buses into public transport networks, Bangladesh can significantly cut emissions while modernising urban mobility.

High-speed connectivity through nationwide 5G deployment would enable a range of smart city applications -- from industrial automation to real-time transport management -- laying the foundation for a digitally integrated urban ecosystem.

Integrated planning, combining advanced technology with green energy solutions and sustainable urban design, can transform city districts into efficient, eco-friendly environments, akin to Hangzhou or Shenzhen.

By adopting and adapting these initiatives, Bangladesh has the opportunity to leapfrog traditional urban development challenges, creating cities that are not only larger but smarter, cleaner, and globally competitive. The synergy of technology, innovation, and sustainable planning could herald a transformative era for the nation’s urban landscape.
