Cities in China and the United States are deepening cooperation on sustainable urban development through sister-city exchanges focused on green innovation and smart governance.

Hangzhou has promoted ecological concepts through its Zero-Waste Asian Games initiative in 2023 and improved urban management with its City Brain digital governance system.

Meanwhile, Richmond in Virginia has expanded bike lanes and sidewalks to create more livable communities, while also exploring hydrogen energy technology to advance environmental protection.

Using green development as a bridge, cities from both countries are learning from one another in sustainable governance, highlighting the human-centered and eco-friendly vision shaping the future of urban life.
