BEIJING, April 16 -- A plan intensifying the government fight against water pollution in China was released Thursday.

The Action Plan for Water Pollution Prevention and Control aims to reduce pollutants, improve drinking water and promote water saving, according to the State Council, China's cabinet.

The aquatic ecosystem has been severely damaged in many parts of China, threatening public health and economic development. Targets for improvements by the end of 2020 include reducing the amount of severely polluted water and containing groundwater contamination.

Specifically, the plan said more than 70 percent of the water in the seven major river valleys, including the Yangtze and Yellow rivers, should be in good condition by 2020. The same target is set for offshore areas.
