Four more Chinese irrigation projects designated world heritage structures

It is important to present the history and culture of Chinese irrigation works and study the science, technology, cultural value and management experience behind them, Chen said, noting that this will help the country's efforts to advance rural revitalization, ecological protection and sustainable water resource utilization.

Along with the four Chinese projects, another 15 irrigation projects in countries including Australia, India and Iraq were also added to the WHIS list, which now covers 140 projects in 18 countries.
