China's top economic planner said it would cut the production and use of plastic over the next five years, helping reduce one of the world's biggest sources of plastic pollution.

By the end of this year, nondegradable plastic bags will be banned in places such as supermarkets and shopping malls in major cities, as well as in the country's ubiquitous food delivery services, according to a plan released by the National Development and Reform Commission on Sunday.

China will significantly reduce the use of disposable plastic in e-commerce, express deliveries and takeout food by 2022, while promoting alternative materials, the NDRC said. The nation will also establish a system for producing, distributing, consuming, recycling and disposing of plastic products by 2025.
